Wherever possible, parents may wish to trace information to its source for the most accurate and current facts. Here is a link to ACT's current webpage on the Explore test: http://www.act.org/products/k-12-act-explore/. The website shares that pre-existing contracts for Explore testing are being honored. Apsire, a longitudinal test for students in grade 3 through early high school, replaces both Explore and Plan.
