How the ACT Predictive Modeling Service Works

Predictive modeling data for ACT score senders are appended to ACT electronic records of score senders to your institution. Predictive modeling data for EOS names selected are appended to EOS records and provided to you when you purchase EOS names.

The Predictive Power of the Student Choice Set

When students take the ACT, they can choose to send their scores to up to six institutions in preference order. ACT calls this mix of campuses the choice set. Through extensive research, ACT has determined that this choice set carries a predictive power in the models that far outweighs other variables.

  • The preference order, or level of college choice, is the single most important factor in predicting that a student will enroll at a specific institution.
  • Likewise, the mix of campuses (in-state or out-of-state, public or private, selective or non-selective) is the single most important factor in predicting whether a student will enroll at an out-of-state institution, predicting whether a student will enroll at a private institution, and predicting the selectivity of the institution at which the student is likely to enroll.
