For the 2018 AP exams, the College Board (CB) piloted an early AP exam ordering deadline with a little over 100 schools. Students were required to register by Nov 1 in order to avoid a $40.00/exam late fee. Students who canceled an exam after the Nov 1 deadline were assessed a $40.00/exam cancellation fee.
According to the CB data there was a 33% increase in the number low-income students taking the exam but only a 20% increase in the number of low-income students receiving a score of 3+ (a score of 3, 4 or 5 may earn students college credit or placement in a higher level course).
Many AP Stakeholders are voicing their concerns, demanding the College Board NOT implement the proposed changes by signing and circulating a petition, https://www.change.org/p/demand-the-college-board-not-mandate-fall-ap-exam-requirements-and-deadlines
