My family has teachers but times are changing.You must have standards set and you must have pre-teachers passing praxis exams just like a lot of professional careers,nursing,etc. The bottom line is if you can not pass these required tests you have no business teaching or nursing. I know you get ample chances to pass them. I think the educational system in Tennesssee needs to gravitate to all teachers having no less than a masters degree. I just think that much time spent preparing you will be more dedicated and educated to teach.
