The number of principals who have signed onto a letter objecting to New York State’s system of teacher evaluations has grown by 85 just since Monday.

The letter, which was posted online, voices objections to a new state evaluation system that will rate teachers and principals based on student scores on standardized tests.

The principals’ complaints include: The system has not been field tested; there are scores to rate only English and math teachers; state tests have repeatedly been shown to be unreliable.

Here are the latest totals, and in parentheses are the totals as of Monday.

Total 841 (from 756)

Long Island 504 (from 502)

New York City 40 (from 35)

Westchester 74 (from 59)

Rockland 24
