That's the finding of a major study done in part by University of Colorado Denver's School of Education.

It finds ProComp has helped improve achievement the most in math and reading among its middle and high schools.

The announcement was made at Skinner Middle School in northwest Denver, whose teachers have earned more than $233,000 in ProComp incentives over the past year. That's more than $11,000 per teacher.

DPS Superintendent Tom Boasberg says it's nice to have an independent study validate the program's success.

More than 80 percent of all DPS teachers, and all new hires since 2006, participate in the program.
