Having a base salary plus incentive pay for meeting objective goals is commonplace. Companies wouldn't do that if it didn't work. In my own company, Zortech, the staff was paid a base rate plus a cut of the gross sales for the month.

Actually the reverse would happen. The best students would automatically attain grade level performance, and likely exceed it. They'll already get the bonus for those students without any effort. The gold is in getting the underachievers to achieve.
