BETHESDA, Md. (WUSA9) -- Superintendent Joshua P. Starr says that Montgomery County Public Schools should not move forward with proposed changes to school start and end times.

Starr cites implementation costs of more than $20 million and mixed feedback from the community. He says it's possible that the issue will be revisited in the future.

"I recommended we study changing bell times because I believe it is an important issue that deserves our attention," Dr. Starr said. "But after receiving the final cost estimates, along with mixed feedback from our community, I do not believe it is feasible or responsible to move forward with these changes at this time. However, we will continue to discuss and monitor this issue."

In October, Starr recommended that MCPS consider shifting high school start times 50 minutes later, shifting middle school start times 10 minutes earlier, and extending the elementary school day by 30 minutes for the health and well-being of students.

Tuesday, Starr released a report of the public input and financial impact of the change in start and end times. The Board of Education will discuss the report on June 17.
