PORTLAND — The new chief academic officer of the city’s public schools will start his job on July 1.

David Galin has been curriculum director of School Administrative Distrct 51 in Cumberland and North Yarmouth for six years.

In the new CAO position, Galin will oversee curriculum and testing to ensure consistency and continuity of academic programs across Maine’s largest district.

The new position is part of Superintendent Jim Morse’s administrative reorganization, which creates some new positions and eliminates others, including assistant superintendents.

Galin, who lives in Portland, will oversee two new curriculum coordinators, one for math and science and another for language arts and humanities.

Under Galin’s guidance, the number of students in SAD 51 who meet or exceed minimum standards in math and reading increased from 60 percent to 80 percent.

Galin’s annual salary, approved by the School Committee last week, will be $115,000.
