Prince George’s County Lead the Way to Merit Pay
Many of the country’s top educators are talking about the idea of paying teachers in line with their performance in the classroom. On Wednesday, Prince George’s County will actually do it.
The second-largest school system in Maryland is paying $1.1 million to 279 teachers and administrators from a dozen schools who volunteered for a new program that links cash bonuses to classroom performance. The amount of money being paid is relatively small, and the number of staff members is a fraction of the 17,000 people employed by the expanding school system. But as a symbol of how attitudes toward compensation are changing, it’s something to be watched.
"I would really like to see this pilot moved to scale," said William R. Hite Jr. , superintendent in Prince George’s. "We feel like we’re on the edge of this, but the key piece of this is that we’re working with our teachers union. "
A. offers extra money based on teaching performance
B. pays bonuses to schools who volunteered for a program
C. judges classroom performance by schools’ financial ability
D. links money paid to the school to it’s classroom conditions
