How a class works
Step 1
Make the class
Sign in, pick HTL 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
The ASCP HTL and HT exams have 100 multiple-choice questions in 2 hours 30 minutes, delivered by computer adaptive testing. Scores are scaled from 100 to 999 and 400 passes. Staining is the largest area at 30 to 40%.
Tigertest's practice follows the ASCP BOC content guideline (rev. September 2025). Students train in short sets where missed questions come back until they are mastered, then take full practice tests.

Questions teachers ask
Is the HTL 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 HTL 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.
