Board of Finance Chairman Jon Zagrodzky is being criticized by some parents of Darien special education students who imply that he’s attacking special education spending. The accusations are exaggerated, sometimes inaccurate and occasionally nonsense. Readers can see that for themselves in the excerpt of his speech we’ve published at the bottom, and compare that with what the letters said. Zagrodzky’s public office concerns town spending, and education spending takes up most of what taxpayers fork over to the town. Special education spending alone, as he noted, has a budget of roughly $24 million — a quarter of the entire education budget.
