Further Detail

  • Essays are not included on the SAT/ACT Diagnostic.
  • Specifications are subject to change.
  • Please remember: The SAT/ACT Diagnostic is designed to help students determine whether they’re better at the ACT or the SAT. It is not designed to generate precise scores that predict how they will do on the actual SAT or ACT. The generated comparison scores reflect how a student did on the diagnostic the day that he or she took the diagnostic.
