Special education in Connecticut

Questions worth asking

1. 18.1% of Connecticut's students have an IEP, 2.7 points above the nation (15.3%). How do referral, evaluation and eligibility practices shape that share?[1][3]
2. 6.4% of students with IEPs learn in separate settings, against 2.8% for the nation. What share of special education spending follows those placements?[2]
3. Spending per student is $24,832, against $17,314 for the nation. How much of the difference is cost of living, staffing levels or special education services?[6]

These figures describe; they do not explain. Each question is a starting point for a conversation, not a finding.

Both parts. Rates use only the districts that reported both parts of the fraction. A district missing either part is left out of that rate, never counted as zero.

Not published. Not published means the publisher suppressed the figure to protect student privacy, did not report it, or the count is fewer than 10 students. It is never zero.
