Make the class
Sign in, pick STAAR Biology and name the class. It takes under a minute.
Step 2
Post one link
Put the class link in your LMS, a slide or a group chat. Students join with just the name you know them by.
Step 3
See what to reteach
Open the class page for scores, who practiced, and the topics and questions the class misses most.
What your students practice
STAAR Biology is the Texas end-of-course test for high school Biology, given by the Texas Education Agency. On the blueprint effective beginning with the Spring 2026 administration it has 33 to 35 questions worth 40 points in four strands: Biological Structures, Functions, and Processes (12 to 14 questions), Mechanisms of Genetics (7 to 9), Biological Evolution (7 to 9) and Interdependence within Environmental Systems (5 to 7). Question types include multiple choice, multiselect, drag and drop, hot spot, inline choice, match table grid, text entry and short constructed response, and some come in cluster sets that share a scenario. There is no fixed time limit: students are expected to finish in about three to four hours, within the school day. A calculator is required. On the Spring 2026 test, Approaches Grade Level began at a scale score of 3550, Meets at 4000 and Masters at 4570.
Tigertest's practice follows TEA's Biology STAAR Blueprint (effective Spring 2026), the Biology assessed curriculum (2025-2026), the 2026-2027 STAAR Test Administrator Manual and the Spring 2026 Biology raw score conversion table. Students train in short sets where missed questions come back until they are mastered, then take full practice tests.

Questions teachers ask
Is the STAAR Biology class free?
Yes. Classes are free for teachers. A student in your class also gets that test's full stats and every step of it at no charge.
Do my students need accounts?
No. A student opens your class link, types the name you know them by and starts practicing. An account is optional and keeps their progress across devices.
What do I see as the teacher?
Who practiced and when, each student's practice test scores, the STAAR Biology topics the class is weakest on, and every question the class answered with how many missed it and which wrong answer they picked.
Can I use my own questions too?
Yes. Any account can turn its own material into a Tigertest quiz and limit it to one class, so only your students can play it.
