New city statistics are showing a steep decline in parent involvement in New York public schools, giving potential ammunition to critics who say the Department of Education under Mayor Michael Bloomberg has been unresponsive to families.
City officials attributed part of the plummet to a new data-collection system. But critics, including some possible mayoral contenders, said the numbers in the annual Mayor’s Management Report were hard evidence of long-held frustrations by public-school parents.

I wonder if Madison PTO attendance patterns have changed? During the 2000’s, most meetings that I observed or participated in typically had no more than 12 to 15 parents. Often less than 10 appeared.
One meeting sticks out. More than 50 parents attended a Thoreau PTO meeting which attempted to bring Singapore Math to the school. That was a spectacular failure, unfortunately.
