Jenison juniors take the PSAT at school during the fall and the SAT at school during the spring. If a student chooses to re-take the SAT or to take the ACT, they are responsible for registering for the test through College Board.
Jenison High School provides preparatory opportunities for the SAT test. Another excellent resource to prepare for the SAT is Khan Academy.
