The Texas Success Initiative (TSI) Assessment is a state-mandated test used by Texas public colleges and universities to determine whether entering students are ready for college-level coursework in mathematics, reading, and writing. The TSI is a placement test — not an admissions test — administered after a student is admitted to a Texas public institution of higher education. TSI results determine whether a student places into college-level courses directly or must complete developmental (non-credit) coursework before taking college-level classes.
The TSI Assessment is administered by Texas public two-year and four-year colleges and is a requirement of the Texas Success Initiative — state law requiring that Texas public institutions assess students' academic readiness and provide support services to students who are not yet college-ready. The assessment is administered by College Board (the same organization that administers the SAT and AP exams) on behalf of the Texas Higher Education Coordinating Board (THECB).
The current version of the TSI Assessment is TSI Assessment 2.0, implemented in January 2021. TSI 2.0 replaced the previous TSIA (TSI Assessment 1.0). TSI 2.0 uses Diagnostic Branching — an adaptive testing approach where your initial responses determine the difficulty of subsequent questions, providing more precise placement information than fixed-form tests. Understanding how TSI 2.0 differs from older TSI versions prevents candidates from using outdated preparation materials.
Texas law generally requires all entering students at Texas public colleges and universities who plan to enroll in college-level academic coursework to complete the TSI Assessment before enrollment — unless they qualify for an exemption. TSI requirements apply to students enrolling in credit courses, not dual credit high school courses taken through community colleges (though dual credit rules vary by institution).
Texas law provides exemptions from the TSI Assessment for students who meet certain academic performance thresholds on other standardized tests. Current TSI 2.0 exemption criteria include: SAT — a combined SAT score (Evidence-Based Reading and Writing + Math) of 1070 or higher with a minimum score of 500 in each section exempts from both TSI Reading and Math; ACT — a composite score of 23 or higher with a minimum subject score of 19 in English and Math sections individually; STAAR — End of Course (EOC) test scores for English II (4000+) exempt from TSI Reading; STAAR Algebra II (4000+) exempt from TSI Math; AP Exam — a score of 3 or higher on an AP English Language, AP English Literature, or AP Calculus exam; IB Exam — a score of 4 or higher on Higher Level IB English or Mathematics exam; College-Level Coursework — successful completion of a college-level Math or English course (grade of C or better) at an accredited institution; and Military — individuals currently serving on active duty or who have been honorably discharged within the last three years are typically exempt. Exemption criteria are set by the state — verify current thresholds with your specific institution, as individual colleges may have additional exemption pathways.
TSI 2.0 consists of three sections: Mathematics, Reading, and Writing. There is no time limit for the TSI Assessment — students have as much time as needed to complete the test. The test is computer-based and administered at campus testing centers or approved testing locations.
The TSI Mathematics section assesses: Quantitative Reasoning — applying mathematical concepts including ratios, proportions, percentages, rates, and basic statistics to real-world problems; Algebraic Reasoning — interpreting and building algebraic expressions and equations, solving linear and quadratic equations, and understanding functions; Geometric and Spatial Reasoning — applying geometric concepts including area, perimeter, volume, angle relationships, and coordinate geometry; Probabilistic and Statistical Reasoning — interpreting data from graphs, tables, and statistical displays; and, for students who demonstrate college readiness on the initial portion, an Extended Mathematical Reasoning (EMR) diagnostic module covering more advanced algebra, functions, and statistical reasoning. TSI 2.0's Diagnostic Branching means that initial questions are at a general level — if you demonstrate strength, you will receive the EMR module which can place you directly into higher-level math courses like College Algebra or Precalculus.
The TSI Reading section assesses: Literary Analysis — understanding and interpreting literary texts (fiction, poetry, drama); Main Idea and Author's Purpose — identifying main ideas, themes, and author's intent in informational passages; Inferences in a Text or Texts — drawing logical inferences from passages; and Use of Evidence in a Text or Texts — identifying how authors use evidence to support claims. Reading passages come from a variety of genres and subject areas — literary, humanities, social sciences, and natural sciences. As with Mathematics, the Reading section uses Diagnostic Branching — initial performance determines whether the student receives additional diagnostic modules.
The TSI Writing section has two components: Multiple-Choice Component — assesses sentence structure (fragments, run-ons, comma splices), agreement (subject-verb and pronoun-antecedent), verb tense consistency, punctuation (commas, semicolons, apostrophes), and revision of sentences for clarity and conciseness; and Essay Component — a 5-paragraph persuasive essay in response to a prompt on a general interest topic. The essay is scored from 1 to 8 by human readers. College readiness requires a score of at least 340 on the multiple-choice component AND an essay score of 5 or higher — both thresholds must be met simultaneously. Students who meet the multiple-choice threshold but not the essay threshold (or vice versa) are not considered college-ready in writing.
TSI 2.0 scores range from 310 to 390 for the multiple-choice components. College readiness cutoff scores for TSI 2.0: Mathematics: 350 or higher = college-ready; Reading: 351 or higher = college-ready; Writing: 340 or higher on the multiple-choice section AND a 5 or higher on the Essay = college-ready (both thresholds required).
Students who do not meet the college-ready cutoffs are considered 'not college-ready' (NCR) and are required to enroll in developmental education before taking college-level courses in the subject where they did not meet the threshold. Developmental education options vary by institution: standalone developmental courses (non-credit, may extend time to graduation); co-requisite courses (pairing a developmental support course with the college-level course); and intensive tutoring and intervention programs. Many Texas colleges use co-requisite models — these are preferred because they allow NCR students to take college-level courses with additional support, rather than delaying entry into credit coursework. Check with your specific institution for its developmental education approach.
Students who do not achieve college-ready scores can retake the TSI Assessment. Most institutions allow multiple retakes, though they may require evidence of preparation (completion of developmental coursework or tutoring) before allowing a retest. Retake policies vary by institution — some charge a retesting fee; others allow free retakes. Improving TSI scores on a retest requires targeted preparation in the specific areas where you fell short.
TSI preparation should focus on the specific skill areas tested, particularly for candidates who are not strong in math or have been out of school for some time. Effective TSI preparation combines content review with timed practice tests.
Khan Academy is the best free resource for TSI Math preparation. Khan Academy's content covers all TSI math content areas comprehensively — basic arithmetic, ratios and proportions, algebraic expressions and equations, functions, geometry, statistics, and probability. The 'Get ready for Algebra 1' and 'Get ready for College Algebra' sections are particularly relevant. Identify your weak areas using a TSI practice test, then focus Khan Academy study on those specific topics. For candidates who struggle with algebra, consistent daily practice of 30 to 60 minutes over 4 to 8 weeks builds the fluency needed to reach the 350 cutoff.
For TSI Reading: practice passage-based reading comprehension, focusing on identifying main ideas, author's purpose, and text-supported inferences. Reading informational articles and op-eds daily builds the comprehension skills tested. TSI Reading does not have a calculator or reference sheet — it tests pure reading comprehension. For TSI Writing: review grammar conventions tested (sentence structure, agreement, verb tense, punctuation) using targeted grammar review resources; and practice timed essay writing. The TSI essay is scored on organization, development of ideas, and standard English conventions. Practice writing 5-paragraph essays on general topics with a clear thesis and supporting examples — aim for essays that take 25 to 35 minutes to write.
