IF YOU CAN'T TEACH TO THE TEST YOU AREN'T DOING YOUR JOB:

Teachers’ Unions vs. Progress—Again: New York resists reforms that would bring in millions and improve teacher quality. (Marcus A. Winters, 14 December 2009, City Journal)

The use of data to improve student learning is a crucial modern education reform. Standardized tests produce rich sources of information that researchers can use to identify effective policies and practices. The data revolution, moreover, promises to move education policy away from politics. Numbers don’t have agendas or run for reelection. Accurately collected and properly analyzed, data can reveal truths that escape our sight.

One such truth is the effectiveness of individual teachers. Data analysis is far from perfect, and no one argues that it should be used in isolation to make employment decisions. But modern techniques can help us distinguish between teachers whose students excel and teachers whose students languish or fail. There’s just one problem with the data revolution: it doesn’t work without data. States must develop data sets that track the individual performance of students over time and match those students to their teachers.

Unfortunately, New York has deliberately refused to take that step.
