The Combined English Language Skills Assessment (CELSA) is a standardised fill-in-the-blank placement test used by colleges and universities across the United States to determine the appropriate ESL course level for incoming students. Scoring well on the CELSA means placement in a higher-level course — saving you time, tuition, and the frustration of repeating material you already know. Our free CELSA practice test PDF gives you targeted practice with the grammar, vocabulary, and reading comprehension skills that the test measures, along with a clear explanation of how scores translate into placement levels.

CELSA grammar questions are fill-in-the-blank items embedded in complete sentences or short passages. You are given a sentence with a blank and must select or supply the word or phrase that makes the sentence grammatically correct. The grammatical structures tested increase in complexity as you move through the 80 items, which is why early accuracy is important — each item builds on the assumption that you have mastered the preceding level.
Verb tenses are the single most tested grammatical category on CELSA. You must distinguish between simple present, present progressive, simple past, past progressive, present perfect, past perfect, and future tenses, and know when each is appropriate based on contextual time markers in the sentence. Common traps include the difference between "have done" (present perfect, result matters) and "did" (simple past, time is specified), and the use of "was/were doing" versus "did" for interrupted past actions.
Subject-verb agreement failures are a reliable source of CELSA errors for test-takers. Collective nouns (team, committee, family), indefinite pronouns (everyone, nobody, each), and inverted sentence structures all generate agreement questions. Articles present similar difficulty: the rules governing "a" versus "an" versus "the" versus zero article are notoriously hard to internalise because native speakers apply them intuitively rather than analytically. Preposition usage — particularly the prepositions of time (at, on, in), place (at, on, in), and movement (to, into, onto) — rounds out the grammar content that test-takers most frequently find challenging.
CELSA vocabulary questions ask you to identify the word that best fits the meaning of a sentence. These are not isolated vocabulary definitions — they test whether you can use context clues (surrounding words, sentence logic, paragraph theme) to determine which option is semantically appropriate. Academic vocabulary at the B1–B2 CEFR level is most commonly targeted, including terms related to education, work, daily life, health, and civic matters.
Morphology knowledge helps significantly with vocabulary questions. Understanding prefixes (un-, dis-, re-, pre-), suffixes (-tion, -ment, -ful, -less, -ous), and roots (port = carry, aud = hear, vis = see) allows you to deduce the meaning of unfamiliar words from their component parts. This strategy is especially effective for test-takers who have strong literacy in a Romance language, since a large share of academic English vocabulary derives from Latin and French roots.
Reading comprehension items on CELSA require you to extract main ideas, infer meaning, identify the author's purpose, and understand referential pronouns (identifying what "it," "they," or "this" refers to). Passages are relatively short — typically one to three paragraphs — and the questions test depth of understanding rather than speed of reading. Practising active reading strategies such as annotating topic sentences, identifying signal words (however, therefore, in contrast, as a result), and paraphrasing each paragraph in your own words will improve both accuracy and reading speed under timed conditions.
CELSA comes in two parallel versions: Form A and Form B. Both consist of 80 fill-in-the-blank questions and must be completed within 60 minutes, giving you an average of 45 seconds per item. The two forms are designed to be equivalent in difficulty and are used interchangeably so that colleges can administer one version as a placement test and the other as a retake without giving an advantage to students who have already seen the questions.
The test is typically administered in a supervised classroom or testing centre setting, on paper. Electronic versions are used at some institutions. No dictionaries, translators, or other reference materials are permitted. Unlike some standardised tests, CELSA does not apply a penalty for guessing, so you should always answer every item even when uncertain. Eliminating one or two clearly wrong options before guessing significantly improves your expected score on items you find difficult.
Test administration policies — including whether makeup tests are available, how results are communicated, and how long scores remain valid — vary by institution. Contact your college testing centre directly to confirm the specific procedures in place at your school.
CELSA scores typically range from 0 to 80 (one point per correct item). Each institution maps score ranges to its own ESL course sequence, but the general framework is consistent. Scores below approximately 20 usually indicate placement in the lowest foundational ESL level, covering basic sentence structure and beginner vocabulary. Scores in the 20–40 range typically correspond to intermediate ESL coursework. Scores of 40–60 generally align with high-intermediate or advanced ESL, and scores above 60 often qualify students to bypass ESL entirely and enrol directly in college-level English composition.
If your goal is to place into the highest possible level, or to avoid mandatory ESL altogether, focus your preparation on the grammar and vocabulary structures that appear most frequently in the upper third of the test. These include complex sentence subordination, academic vocabulary, and nuanced article and preposition usage. Timed practice is critical: 60 minutes for 80 questions is tight enough that slow readers who pause too long on difficult items may not finish.
Effective study strategies for non-native speakers include: daily reading of English-language news articles (annotate unfamiliar vocabulary), grammar exercises targeting verb tenses and article usage specifically, and regular exposure to academic listening (podcasts, lectures) to build intuitive pattern recognition. For the CELSA specifically, doing timed mock tests — answering 80 items in 60 minutes under realistic conditions — is the single most reliable predictor of score improvement. Identify the question types where you consistently lose points and dedicate extra practice sessions to those areas.
