What does \u2018evidence-based practice\u2019 (EBP) mean? There are varying definitions of EBP among the fields of special education, speech language pathology, and behavior analysis. In Evidence-based Practices in Education <\/em><\/strong><\/a>(2012) authors Cook, Smith, and Tankersley define EBP as practices that are shown to be effective through high-quality research to meaningfully improve student outcomes.<\/p>\n

The American Speech and Hearing Association (ASHA) <\/strong><\/a>defines EBP as the integration of clinical expertise\/expert opinion, evidence gathered from the scientific literature and from client observation and data collection, as well as client\/patient\/caregiver perspectives. \u201cWhen all three components of EBP are considered together, clinicians can make informed, evidence-based decisions and provide high-quality services reflecting the interests, values, needs, and choices of individuals with communication disorders\u201d (ASHA).<\/p>\n

In the peer-reviewed journal Behavior Analysis<\/em><\/strong><\/a>, <\/strong>Slocum et al. <\/strong>(2014) define EBP as a model of professional decision-making in which practitioners integrate the best available evidence with client values\/context and clinical expertise in order to provide services for their clients.<\/p>\n

The National Professional Development Center on Autism Spectrum Disorder (NPDC on ASD)<\/strong><\/a> identifies inclusion criteria for EBPs based on the necessity of having a sufficient number of empirical demonstrations of efficacy through high quality, peer-reviewed journal articles and replications of those demonstrations by independent research groups. To be identified as evidence-based, a category of practice must have at least:<\/p>\n
