Identify internal or external rewards that affect recruitment and retention of quality teachers

2 answers

salary
bonus, if any, for rewards.
retirement benefits
fringe benefits
This should get you started.
DrBob222 has given you external rewards. Internal rewards would deal with personal satisfaction factors in teaching.

I searched Google under the key words "internal motivation vs external motivation" to get this:

In the future, you can find the information you desire more quickly, if you use appropriate key words to do your own search. Also see http://hanlib.sou.edu/searchtools/.

I hope this helps a little more.
