How much would you expect to make with a Masters degree and/or after having worked at any profession for 30+ years Bum? Unlike other professions where there is bonus pay for over-achievers and promotions to a higher level position....the only way to make more money as a teacher is to get out of the classroom and become a specialist or an administrator...there are teachers who have been teaching in TX for close to 20 years who are the top of their game and still make less than 52K per year...not more than an average teacher....besides personal drive, which crashes hard in the face of 70+ hour work weeks, tyrannical principals, a mountain of paperwork, helicopter parents, and low to no-motivated students, where is the incentive to over achieve?
