In contrast with professional norms and best practices, the legal requirements for functional behavioral assessments (FBAs) and behavior intervention plans (BIP) are meager in scope and specificity (Collins & Zirkel, 2017). Section 504 of the Rehabilitation Act (2017) makes no mention of FBAs or BIPs, and the Individuals with Disabilities Education Act (IDEA) only requires them, in tandem with manifestation determinations, for disciplinary changes in placement. The line of court decisions that interpret and apply the IDEA, including its corollary state laws, to FBAs and BIPs has continued unabated. Two successive empirical analyses have traced the frequency and outcomes of the court decisions with rulings specific to FBAs or BIPs under the IDEA. The first of these two analyses covered the period from January 1, 1998 to December 31, 2010 (Zirkel, 2011). This analysis revealed that both the number of court decisions and the proportion in favor of the defendant districts steadily increased during this 13-year period. For the entire period, the outcomes distribution of the 56 rulings were 75% for districts and 25% for parents. The second analysis covered the period from January 1, 2011 to December 31, 2016 (Zirkel, 2017). Using the same selection, this analysis found 91 court decisions, which averaged 15.2 per year as compared with 4.3 per year for the previous period. The purpose of this article is to provide a follow-up analysis of the relevant court rulings from January 1, 2017 to June 30, 2020. [For the second analysis, see EJ1139783.]
