1.2 Test Structure, Adaptive Delivery, Routing, and Test-Day Tools

Test Structure, Adaptive Delivery, Routing, and Test-Day Tools

Quick Summary: Each TSIA2 subject begins with a multiple-choice College Readiness Classification (CRC) test scored 910–990. A student who scores below the benchmark continues into a 48-question Diagnostic Test in the same session. In ELAR, a WritePlacer essay is also required for a college-ready result. The multiple-choice tests are computer adaptive, the assessment is untimed, and the testing platform provides any calculator you are allowed to use.

The Two Subject Suites at a Glance

Accommodated versions (paper, large print, braille, audio) are fixed-form linear tests rather than adaptive ones. Otherwise they measure the same content.

Mathematics CRC Blueprint (20 Items)

The College Board Mathematics Test Specifications (v1.4) fix the count in each content category:

The Mathematics Diagnostic has 12 items in each of the four strands. It also includes content that does not appear on the CRC: basic operations with whole numbers, integers, decimals, and fractions; rounding; comparing numbers in different forms; identifying units of measurement; types of angles; sorting and counting data; and building simple graphs and tables.

ELAR CRC Blueprint (30 Items)

The ELAR Test Specifications (v1.4) split the CRC evenly between reading and writing. Reading-focused items come first, and there is no break between the two halves:

• 15 reading-focused items: one 4-item Literary Text Analysis set, then 11 discrete Informational Text Analysis and Synthesis items. Two of the 11 are synthesis items built on paired argumentative passages. The other 9 are chosen by the algorithm from the remaining informational varieties: main ideas and details, inferences, author's craft, and vocabulary.
• 15 writing-focused items: one 4-item Essay Revision and Editing set (development, organization, effective language use, Standard English conventions), then 11 discrete Sentence Revision, Editing, and Completion items (grammar, usage, and punctuation).

Reading passages run from about 40 to 400 standard words, with one passage in the 350–500 range. Most are informative or explanatory, with some narratives and occasional arguments. Writing passages run from single sentences up to about 350 standard words.

The ELAR Diagnostic has 48 items. The 24 reading items include three 4-item literary sets and 12 discrete informational items (2 of them synthesis). The 24 writing items include three 4-item essay revision sets and 12 discrete sentence items. Diagnostic-only content includes decoding and word recognition, spelling and capitalization, purpose and organization, and sentence combining. The profile reports two strands: Text Analysis and Synthesis (reading) and Content Revision and Editing for Conventions (writing).

How Routing Works

Mathematics

1. Everyone starts with the Math CRC.
2. A CRC score at or above 950 ends math testing with a college-ready result.
3. A CRC score below 950 routes the student to the Math Diagnostic.
4. A diagnostic level of 6 is a college-ready result. A level of 5 or lower produces a diagnostic profile.

ELAR

1. Everyone starts with the ELAR CRC.
2. A CRC score at or above 945 routes the student to the Essay.
3. A CRC score below 945 routes the student to the ELAR Diagnostic.
4. A diagnostic level of 4 or higher routes the student to the Essay. A level of 3 or lower ends testing with a not-college-ready report.
5. Only diagnostic levels 5 or 6 can combine with an essay score of 5 or higher for a college-ready result. A level-4 student still writes the essay but cannot be classified college ready on that attempt.

Students must finish every test they are routed to before any results are released. In most cases the score report appears right after testing.

What "Computer Adaptive" Means for You

On the adaptive multiple-choice tests, the platform picks each next question based on how you answered the earlier ones. Correct answers tend to bring harder questions, and incorrect answers bring easier ones. The system places your performance on a common ability scale. The diagnostic tests are calibrated to the same scale as the CRC. Practical consequences:

• Questions appear one at a time, and the test builds its estimate from each submitted answer. Treat every answer as final before you submit it.
• Getting harder questions is normal, not a sign that you are failing. Stay steady.
• Accuracy matters more than speed, because the test is untimed.

Time, Breaks, and "Save and Finish Later"

• Untimed: THECB's student brochure states that there is no time limit for completing the assessments. Testing centers still keep operating hours, so ask how long your appointment window is.
• Save and finish later: You may stop at certain points if you are tired or need a break. If you do, you must return and finish within 14 calendar days. This option is not available for the Essay Test, which must be started and finished in one session.
• Accommodations: Extended time, breaks, and on-screen calculators are already built into the standard test for everyone. Students with documented disabilities request other accommodations through the institution's disability services office. High school students go through their counselor. Accommodated forms include regular or large-print paper, braille, and audio.

Calculators and Other On-Screen Tools

• No handheld calculators of any type may be used on the online TSIA2 Mathematics test.
• Some, but not all, math questions include a pop-up calculator: basic (four-function), square root, and/or graphing, depending on the item. If an item shows no calculator icon, plan to compute by hand.
• Students taking an accommodated paper, braille, or audio test may use a square-root calculator.
• A highlighter tool is available. The TSIA2 Student Portal includes tutorials for the calculator and highlighter tools.
• For the essay, you may ask the proctor for plain scratch paper, which is collected at the end. Dictionaries and other outside resources are not allowed.
