Advanced Placement courses are offered at M-DCPS for students to acquire college credit or advanced college academic standing. A system has been developed in the past by the College Board to use the PSAT for 10th grade students to estimate their potential for AP Examination success. The same test has recently been applied in this district to 9th graders for the same purpose. In this paper we present an alternative, more reliable, prediction system using Florida Comprehensive Assessment Test (FCAT) scores that is appropriate for the prediction of AP Examination success for both 9th and 10 graders. The prediction system should also prove useful for academic counseling and placement purposes. AP Potential Expectancy Tables are attached. (Contains 2 tables.)
