CILS, the Certificazione di Italiano come Lingua Straniera, is issued by the Università per Stranieri di Siena (University for Foreigners of Siena) and is, by most accounts, the single most widely chosen Italian language certification, reportedly accounting for more than half of all official Italian exam-takers worldwide. It was also the first Italian certification to apply the full six-level CEFR framework, and remains the reference point many other institutions, and many learners researching certification for the first time, compare against.
This guide covers CILS specifically: its level structure and naming conventions, exam format and components, who it's typically used for, how to register, and how to prepare effectively. If you haven't already read the Italian Exams hub overview, it's worth doing so first, since it covers the broader context, comparison with the other three certifications, and general guidance on choosing between them that applies regardless of which specific certification you ultimately pursue.
CILS Levels and Naming
CILS uses its own naming convention for the six CEFR levels, which can initially seem unfamiliar compared to certifications that name levels directly by CEFR designation. CILS A1 and CILS A2 correspond directly to CEFR A1 and A2. From there, the naming shifts: CILS UNO corresponds to B1, CILS DUE to B2, CILS TRE to C1, and CILS QUATTRO to C2, using Italian numbers (uno, due, tre, quattro: one, two, three, four) rather than the letter-number CEFR designations directly.
| CILS Name | CEFR Level | Typical Use |
|---|---|---|
| CILS A1 | A1 | Basic proficiency |
| CILS A2 | A2 | Residence permit (certain categories) |
| CILS UNO | B1 | Citizenship applications |
| CILS DUE | B2 | University admission |
| CILS TRE | C1 | Advanced academic/professional use |
| CILS QUATTRO | C2 | Near-native mastery |
CILS also offers some specialized exam variants worth knowing about. CILS UNO has specific versions tailored for different candidate groups, including a variant specifically designed for citizenship applicants (sometimes referred to as CILS UNO – B1 Cittadinanza) and a variant for adolescent candidates (CILS UNO – B1 Adolescenti), reflecting the fact that the exam's content and register can be calibrated somewhat differently depending on the candidate's age and specific purpose for taking the exam.
If you're taking CILS UNO (B1) specifically for citizenship purposes, confirm you're registering for the citizenship-specific variant if one is offered at your exam center, since this version is calibrated to the specific legal requirement rather than being a general B1 assessment.
Exam Structure and Components
The CILS exam evaluates four core linguistic competencies, generally organized into distinct test sections: listening comprehension, reading comprehension, written production, and oral production, with an additional section testing grammatical and lexical competence (correct, precise use of grammar and vocabulary) included at most levels as a distinct, separately scored component.

Each section is evaluated independently, meaning you need to achieve the required minimum score in each individual section to pass the exam overall; a strong score in reading comprehension cannot compensate for a failing score in oral production, for instance. This section-by-section structure has a practical upside if you don't pass on your first attempt: CILS generally allows you to retake only the specific sections you didn't pass, rather than repeating the entire exam, which considerably reduces the cost and time investment of a retake.
Task types vary across the exam and include multiple-choice questions, particularly common in listening and reading sections, semi-structured tasks that ask you to reorganize, complete, or rework a given text based on specific elements provided, and fully open tasks, such as writing an original essay or letter on a given topic, or participating in an unscripted, examiner-led conversation for the speaking component. Higher levels naturally include more open, less structured tasks, reflecting the more sophisticated, independent language production expected at advanced levels.
Who Takes CILS, and Why
CILS candidates span the full range of purposes covered in the Italian Exams hub overview: citizenship applicants satisfying the B1 minimum requirement through CILS UNO, prospective university students satisfying admission requirements through CILS DUE (B2) or higher, professionals and immigrants satisfying specific employment or residence requirements at the level relevant to their situation, and learners pursuing certification simply to formally document their proficiency for personal or professional reasons unrelated to a specific legal or institutional requirement.
CILS's particular strength, the sheer scale of its international exam center network, reportedly over 800 locations worldwide, makes it an especially practical choice for candidates outside Italy who want a certification option genuinely accessible near where they live, rather than needing to travel significant distances or wait for infrequent sessions at a more geographically limited certifying body.
Registration and Exam Sessions
CILS exams are typically offered multiple times per year, commonly in June and December as the two primary sessions, though some exam centers and levels offer additional sessions beyond these two main dates. Registration is handled either directly through the University for Foreigners of Siena's official channels or through an authorized local exam center, such as an Italian cultural institute or affiliated language school in your area, and it's essential to register through your specific local center's process rather than assuming a single universal registration procedure applies everywhere.
Registration windows typically open a couple of months before the exam date and close several weeks beforehand, and exam fees vary by level, generally increasing for higher CEFR levels given the more extensive assessment involved at those levels. Because exam dates and registration windows are set by each authorized center and can vary by location and year, confirming the current calendar directly with your specific exam center, rather than relying on a fixed assumption about when sessions occur, is an essential step in planning your preparation timeline.
How to Prepare for CILS Specifically
Beyond the general Italian proficiency built through the material in Learn Italian, particularly Italian Grammar and Italian Vocabulary for the written and grammatical competence sections, and Italian Conversation and Italian Pronunciation for the oral component, CILS-specific preparation benefits considerably from working through official or reputable practice materials calibrated to CILS's actual task formats, since familiarity with the specific structure of CILS tasks, as distinct from the other three certifications' somewhat different formats, meaningfully affects exam-day performance and confidence.
Time management within the exam is worth specifically practicing, since CILS, like most structured language exams, allocates fixed time limits per section that can feel tight if you're not already familiar with the pacing required, particularly for the writing and grammatical competence sections at higher levels, where the volume of required output increases noticeably from level to level. Practicing under realistic timed conditions, rather than only studying the underlying language content without time pressure, helps build the specific exam-taking stamina and pacing instincts that a strong general Italian foundation alone doesn't automatically provide.
What Each CILS Level Actually Requires
Understanding the practical communicative demands of each CILS level helps you choose an appropriate target rather than guessing based on level names alone. CILS A1 and A2 test basic survival communication: understanding simple, frequently used phrases and expressions, introducing yourself and others, and handling very simple, predictable exchanges about immediate needs, similar in spirit to the foundational material covered in Italian for Beginners.
CILS UNO (B1) tests independent, if imperfect, communication across familiar everyday topics: describing experiences, expressing opinions and plans with reasonable clarity, and handling most travel and daily life situations without needing to fall back on a companion or translator. This is the level specifically required for Italian citizenship applications, and candidates preparing for this purpose specifically should focus on the practical, everyday communicative competence this level actually tests, rather than over-preparing for more abstract or academic language that exceeds what's required.
CILS DUE (B2) raises the bar to comfortable, largely autonomous language use: understanding extended discourse on both familiar and unfamiliar topics, producing clear, detailed text on a range of subjects, and participating in extended conversation with good fluency, without needing to frequently search for words or restructure sentences mid-thought. This is commonly the level required for university admission to Italian-language degree programs.
CILS TRE (C1) and CILS QUATTRO (C2) test advanced and near-native mastery respectively: nuanced expression of subtle shades of meaning, sophisticated use of register and idiom, and the kind of flexible, precise language control typically associated with extensive immersion or advanced academic study, relevant for specialized professional contexts, advanced academic positions, or candidates aiming to formally document a very high level of acquired proficiency.
Sample Task Types by Section
Getting a concrete sense of what CILS tasks actually look like helps demystify the exam considerably. In the listening section, you might hear a short recorded announcement, conversation, or radio segment and answer multiple-choice or short-answer questions about its content, with the recording typically played a limited number of times, usually once or twice depending on the level, mirroring the real-world constraint of not being able to ask someone to repeat themselves indefinitely.
In the reading section, you might encounter an authentic or semi-authentic Italian text, an article, an advertisement, a short story excerpt, paired with comprehension questions ranging from straightforward factual recall to more inferential questions about tone, intent, or implication, particularly at higher levels. The grammatical and lexical competence section typically involves tasks like filling in missing words in a text, choosing the correct verb form from options, or identifying and correcting errors in a given passage, directly testing the kind of structural knowledge covered in depth in Italian Grammar.
The written production section asks you to produce original text, commonly a letter, an essay expressing and supporting an opinion, or a narrative account of an experience, evaluated on content relevance, organization, grammatical accuracy, and vocabulary range. The oral production section, typically a face-to-face or recorded interview with an examiner, may include a warm-up conversational portion, a more structured task such as describing an image or responding to a specific prompt, and sometimes a role-play scenario testing your ability to handle a realistic, semi-improvised interaction in Italian.
Scoring and What Counts as Passing
CILS, like the other certifications covered in this hub, typically requires achieving a minimum percentage score, often around sixty percent, in each individually assessed section rather than an overall average across the whole exam. This means a candidate who performs exceptionally well in reading but only marginally in speaking does not pass on the strength of an averaged score; each section stands on its own, and falling short in even one section means that specific section needs to be retaken, even if your overall performance across the full exam would otherwise comfortably exceed the passing threshold.
This section-independent scoring structure is worth keeping in mind while you prepare, since it argues against the common, intuitive strategy of over-investing in your strongest skill area at the expense of your weakest. A balanced preparation approach across listening, reading, writing, grammatical competence, and speaking, even if this means spending disproportionate time on whichever skill currently feels weakest, tends to produce a more reliable overall pass than concentrating preparation time on your already-strongest area.
CILS for Citizenship: Specific Considerations
Given how common the citizenship use case is among CILS candidates, a few additional, specific points are worth knowing. The B1 level requirement for citizenship is a legal minimum, not a suggestion, meaning a B1 pass genuinely satisfies the language requirement, and pursuing a higher level purely "to be safe" provides no additional legal benefit for the citizenship application itself, even though it might be personally satisfying or useful for other purposes.
Many candidates pursuing CILS specifically for citizenship purposes benefit from confirming with their specific consulate or relevant Italian authority exactly which documentation format is required alongside the certificate itself, since citizenship application processes can have their own specific procedural requirements beyond simply holding a valid B1-level certificate, and these procedural details are managed by the citizenship application process itself rather than by the University for Foreigners of Siena or the CILS exam system.
Common Mistakes Candidates Make
A handful of avoidable mistakes show up repeatedly among CILS candidates, and knowing about them in advance can meaningfully improve your actual exam outcome. The first is choosing a target level based on ambition rather than demonstrated, tested ability. It's tempting to register for a higher level than you've genuinely confirmed you can handle, particularly if a specific institutional requirement specifies a minimum level and you'd prefer to exceed it comfortably, but registering for a level meaningfully beyond your current proficiency, confirmed ideally through an honest practice test rather than self-assessment alone, often results in a failed attempt and a costly, time-consuming retake, when registering for a level you can confidently pass would have been the more strategic choice.
The second common mistake is neglecting the grammatical and lexical competence section in favor of focusing preparation time on the more communicatively appealing speaking and listening sections. This section, while perhaps less engaging to practice than conversation, is scored independently and requires its own dedicated preparation, generally through the kind of targeted grammar review covered in Italian Grammar combined with CILS-specific practice exercises that mirror the section's actual task formats.
The third is underestimating the time pressure of the written production section specifically, particularly at higher levels where the expected word count and complexity increase substantially. Many candidates who write comfortably and fluently without time constraints during practice find the actual timed exam considerably more challenging, simply because the cognitive load of organizing, writing, and reviewing a piece of original writing within a fixed time limit is a distinct skill from writing ability alone, and one that benefits from specific, repeated timed practice before the actual exam.
Recommended Preparation Resources
The University for Foreigners of Siena publishes official sample exams and past papers for each CILS level directly through its official website, and working through these official materials should generally form the core of your exam-specific preparation, since they represent the most reliable, format-accurate practice available, considerably more useful than third-party materials that may not perfectly mirror the actual exam's current format and conventions.
Many language schools, both in Italy and internationally, offer CILS-specific preparation courses, which can be genuinely valuable, particularly for candidates who benefit from structured guidance, regular practice deadlines, and feedback on practice writing and speaking tasks from an instructor familiar with the exam's specific scoring criteria. For self-directed learners, working systematically through official sample materials, ideally under timed, exam-realistic conditions, paired with the broader skill-building covered throughout Learn Italian, provides a reasonably effective self-study path even without formal coursework.
What to Expect on Exam Day
Arriving with the correct identification document, generally a passport for international candidates, and your registration confirmation, is essential; exam centers typically cannot admit candidates without proper identification matching their registration, regardless of language preparation. Arriving with reasonable time to spare before the scheduled start, rather than rushing in at the last possible moment, helps reduce unnecessary pre-exam stress that can otherwise affect performance, particularly on the speaking component, where composure and confidence meaningfully affect how fluently you communicate.
The listening, reading, written production, and grammatical competence sections are typically administered together in a single sitting, often with brief breaks between sections, while the oral production component is sometimes scheduled separately, occasionally on a different day or at a different time within the same exam period, depending on the specific exam center's logistics and the number of candidates being processed. Confirming your specific schedule, including whether your speaking component is on the same day as the written sections, is worth doing directly with your exam center in advance rather than assuming a single universal format applies everywhere.
After the Exam: Results and Certificates
Results and certificate delivery timelines for CILS vary by exam center and can take anywhere from several weeks to a few months following the exam date, and it's worth factoring this into your planning if you're working against an external deadline. Many candidates can check preliminary results through an online portal before the official physical or digital certificate is issued, though the specific process varies by exam center and is worth confirming directly when you register, so you know what to expect and when, rather than waiting anxiously with no clear sense of the expected timeline.
A Final Word on Choosing CILS
CILS is a strong, well-established default choice for most candidates, particularly given its wide international availability, and choosing it rarely represents a meaningful disadvantage compared to the other three certifications covered in this hub. If a specific institution, university, or consulate has explicitly recommended or required a different certification by name, follow that specific guidance; but absent such a specific requirement, CILS's combination of broad recognition, extensive exam center availability, and well-documented preparation materials make it a genuinely sound default choice for most learners pursuing formal Italian certification for the first time.
It's also worth recognizing that switching between certifications mid-preparation, while not ideal, isn't a catastrophic decision either, since the underlying language skill you're building, solid grammar, a working vocabulary, comfortable listening comprehension, and confident speaking ability, transfers directly regardless of which specific certification's format you ultimately sit. If you've started preparing for CILS specifically and later discover that CELI, PLIDA, or CERT.IT is more conveniently available or specifically required for your situation, the bulk of your preparation work remains valuable; only the exam-specific format familiarity, generally a relatively modest, late-stage addition to your overall preparation, would need to shift to match your new target certification.
Whatever level and timeline you ultimately settle on, treat the CILS exam itself as a milestone within your broader Italian learning journey rather than the endpoint of it. The skills you build preparing for CILS, whether at A2 for an early documentation purpose or C1 for advanced professional use, remain genuinely useful well beyond the exam day itself, continuing to support whatever real conversations, reading, writing, and listening you go on to do in Italian long after the certificate has been issued, delivered, and filed away somewhere safe for future reference.
If you remain uncertain after reading this guide, comparing it directly against the CELI, PLIDA, and CERT.IT guides elsewhere in this hub is the most efficient next step, since seeing all four side by side tends to clarify which specific combination of availability, format, and timing genuinely fits your situation best.
