EXPLORE®, PLAN®, and the ACT

PLAN is the second part of a testing system that starts with EXPLORE and ends with the ACT.

Typically, students take EXPLORE in the 8th or 9th grade, PLAN as 10th graders, and the ACT as juniors or seniors.

All three test you in English, math, reading, and science. However, the material tested in each program gets more difficult.

This is why the top scores are different.

Program Grade Level Composite
Score Range
EXPLORE 8 and 9 1 to 25
PLAN 10 1 to 32
ACT 11 and 12 1 to 36
