Providing accountability as a core professional role includes documenting t
he outcomes of consultations with parents and teachers. Furthermore, these
consultations can serve as building blocks for evaluating overall intervent
ion program effectiveness. We report the use of single-case accountability
designs for examining individual child outcomes and evaluating the Ohio Ear
ly Childhood Intervention (ECI) project. Procedural guidelines (termed PASS
Key) were used to help structure the process of ecobehavioral analysis, col
laborative consultation, and naturalistic intervention design for children'
s learning, developmental, and behavioral problems. The methods serve as ex
amples of functional assessment, accountability, and program evaluation eff
orts appropriate for early intervention consultations. Moreover, the result
s offer evidence for the effectiveness of the ECI model.
