I found that while everyone at my Kaplan audition was hired, some failed out of the training class or not assigned classes. One was too nervous, another not prepared. One was an older man, a high school teacher for 30 years, and a super guy. But after MANY talks, he refused to follow the directions of our trainer and just follow the lesson plans because he enjoyed talking in and about circles, and was let go.
Hint: after teaching at least one period of classes, I asked for more money per hour and they gave it to me! They let me bill 5-6 hours for a <3 hour class because noone else wanted those classes. Sure, I wasn't on their favorites list, but they charge the students plenty for those classes. Stick it to the man!
