Both Veritas and ManhattanGMAT maintain a score standard of 99th percentile (750+) on the GMAT. This is obviously very important, as a high score indicates a mastery of the skills tested by the GMAT.
However, there are many skills involved in teaching a class that do not relate to intelligence or one's GMAT score. Many people that do very well on the GMAT are not naturally gifted in being able to teach others how to do the same.
Manhattan GMAT understands that the high test score is not the only factor of success, so we hire REAL TEACHERS (who have scored a 99th percentile) to teach our courses. To reflect our emphasis on teaching skills, the company rejects 4 out of every 5 applicants who meet the score threshold.
Furthermore, each MGMAT instructor has to go through over 100 hours of unpaid training in order to be able to teach a student. The company can impose such high standards and requirements because it pays $100 an hour to start, the highest in the industry.
If you check any of the job postings online for Veritas instructors, you will see that they may pay a minimum of $40/hr to their instructors and DO NOT require teaching experience.
