The Up-Island Regional School District committee voted on Monday to part ways with food service provider Chartwells at the end of the school year and instead will opt for its own meals program based at the West Tisbury school.

The committee approved $80,000 for the lunch program, which is expected to start next fall. The program accounts for two full-time positions at the West Tisbury school and two part-time positions, one of which will be at the Chilmark school. The committee also voted to have the $100,000 previously approved for the school kitchen expansion come out of excess and deficiency funds.

The vote was 4-1.

School committee chairman Dan Cabot said at first he was apprehensive about funding both projects in the same fiscal year but decided to approve the measure with the use of the excess and deficiency funds.

“It’s a big step,” Mr. Cabot said Tuesday morning. Even more than a means of teaching children about health and eating well, the food program will be “important for reasons of food quality and taste,” he said.
