Between 1993 and 1998 there were 45 published due process hearings and cour
t cases in which parents of children with autism challenged the appropriate
ness of a school district's educational program for their child. These hear
ings and cases involved parental requests for school districts to provide,
fund, or reimburse them for the Lovaas treatment program for their young ch
ildren. The purpose of this article is to examine how these hearings and ca
ses affect the definition of "appropriate" special education programs. Firs
t, we review previous legislative and litigative definitions of a free appr
opriate public education (FAPE). Next, we analyze the Lovaas treatment hear
ings and cases to identify factors associated with winning and losing decis
ions. Finally, we discuss the implications of these decisions to provide gu
idance to schools in adhering to the procedural and substantive requirement
s of a FAPE.
