How the test runs
- Timing: about 2 hours 10 minutes, or about 3 hours 15 minutes with extended time.
- Breaks: optional 5-minute breaks after the first three subtests, and 1-minute pauses after subtests 4 and 5.
- Don’t sit idle. A student who sits idle for 15 minutes in a subtest is removed from the exam.
- Watch the clock. The TACHS Parent Guide notes that many students run out of time.
- Calculator: a basic four-function calculator is built into the test for the portions where it’s allowed. Personal calculators aren’t allowed.
- Scratch paper: allowed for Reading, Written Expression and Mathematics, but not for the Ability section.
