Looks like 99th percentile was a prerequisite for another program.
Kaplan wrote me this email, which says their cut off is 90th percentile:
"Thank you for your interest in joining the Kaplan faculty. After reviewing your application, we are pleased to invite you to the next step of the Kaplan Teacher Hiring Process-an audition...
Teaching or tutoring for Kaplan is a fulfilling and enjoyable part-time job. Most classes meet one to three times a week during evenings and/or weekends and take place over 4 to 10 weeks. Tutoring typically happens in a Kaplan facility or in a student's home, on a mutually-determined schedule. Teaching for Kaplan is a flexible job and most of our instructors teach classes in addition to a full-time work or school schedule.
STEP 1: The Audition
Your first step is to schedule an audition, guidelines and schedules for which you will find attached. Auditions are usually held in groups, as few as two and, sometimes, as many as thirty. Expect that your group will be ten or fewer.
STEP 2: The Interview
Successful auditioners will then be invited to an interview, a one-on-one meeting with a hiring manager.
STEP 3: Kaplan Teacher Development Program (Teacher Training)
A successful interview grants you an invitation to Kaplan training, an evaluative process involving extensive mock teaching and feedback. We will be evaluating and building your test expertise, as well as your ability to engage your class in active learning, to build student motivation and to represent Kaplan well. Upon graduation, new teachers are typically assigned to one class or to one private student. However, as your skills and experience increase, there will be many opportunities for additional assignments.
We require you to have recent test scores in the 90th percentile on the test you wish to teach.. If your test score is not above the 90th percentile or is more than five years old, you may take a proctored practice exam at a local Kaplan center. In any case, an acceptable score is a necessary precondition for successful completion of the Kaplan Teacher Development Program.
After you've read the Audition Guidelines attached, and selected an audition date, please contact me as soon as possible to schedule your audition."

"As a reminder, we ask that you prepare a 5-minute presentation on a non-academic subject. You will be evaluated on your general presentation skills, your comfort level and interaction with your audience, and your adherence to the time constraints. "
