The PLAN test scores range between 1 and 32, with 1 being the lowest score possible and 32 the highest. A good score on the PLAN varies depending on the student and what the desired score is on the ACT, as the PLAN is a practice test for the ACT.
The PLAN test is a preliminary practice test that allows the student to gain perspective on how he might score on the ACT. There are four multiple choice tests included in the PLAN test. These tests cover English, math, reading and science. The overall composite score is the average of the four individual tests.
