HEMPSTEAD - Dozens of Long Island teachers, principals and superintendents met today to challenge the state's new evaluation system, saying that it might not be fair or effective.

The recently introduced system calls for an annual evaluation based on 100 points, 20 percent of which are based on student exams, another 20 percent on student achievement and 60 percent on other criteria, such as independent classroom observation.

Roslyn High School Principal Kevin Scanlon says he often puts his best teachers with the weakest students.

"They are concerned how they are going to be evaluated if they're working with children that really need them, and how that's going to look on paper," he says.

Jeffery Rozran has been teaching English in Syosset for 38 years. He says many of his colleagues might prefer to retire rather than get undeservedly bad evaluations.

Some parents, however, say a stricter evaluation system would result in more accountability.

Teachers rated ineffective for two years in a row based on the point system could lose their jobs.
