Look to U.S. Department of Education Office of Special Education Program’s annual “determinations” for answers.
Every year, states and “entities” are required to evaluate their implementation of IDEA and submit their State Performance Plan and Annual Performance Report (SPP/APR) to USDOE, which subsequently releases determination letters based on SPP/APR in response. There’s a two year lag, so the 2023 determination letters, as an example, reflect the 2021 SPPs/APRs submitted by the states and entities, and provide the determination and basis for determination based on the 2021 period.
While a few states improved their performance, others continued to fail.
In 2023, 23 states or entities met requirements, as compared to 22 in 2022; six states need assistance (one year) in 2023, compared to 3 in 2022; 29 need assistance (two or more consecutive years) in 2023, compared to 35 in 2022; and two states need intervention in 2023, compared to zero in 2022.
