Warren Sapp -- Ex-Hookers Schooled Me On the Street Life

Warren Sapp graduated from the school of hooker hard knocks -- as part of his amazing plea deal in his Phoenix prostitution bust -- and TMZ Sports found out the curriculum.

Sapp got the solicitation charge dropped from the Super Bowl weekend arrest by completing a one day course, and according to his attorney ... the Hall of Famer's class featured some intense guest speakers. Craig Mehrens says Sapp heard from Phoenix PD Vice Squad officers as well as ex-prostitutes.

Both shared their experiences working the streets -- so you might say Sapp got it from both sides ... again.

His next step is getting the assault charge dropped, and Mehrens says Warren will be completing 15 anger management courses over the next few weeks to achieve that. We're told he can attend those classes closer to home in Florida.
