Internships play a pivotal role in the future of school psychology, and internship training is inßu-enced by disciplinary trends including (a) an increased focus on accountability and demonstrating the positive impact of trainees' practices on student outcomes and (b) growing emphasis on scientifically based and empirically based practice. These inßuences also include greater sophistication in decision making as well as different ways of outcome-focused decision making. System-wide approaches such as Positive Behavior Support (PBS) and response to intervention (RTI) require high training demands to develop intervention-related decision and accountability skills. Programmatically, accountability systems to meet the training needs of intervention services require scaling up. This article describes a multiyear developmental project bringing diverse universities together to institutionalize a statewide system of accountability. We share data from 3 years (N of interns = 278) and suggest recommendations for outcome-oriented evaluation for other universities, agencies, school psychological services delivery units, or states. C 2009 Wiley Periodicals, Inc.Forces that drive accountability movements in education and psychology have a great impact on the Þeld of school psychology. Although accountability has played a prominent role in the educational reform efforts of the past 50 years (Linn, 2000), the No Child Left Behind Act (NCLB) (PL 107-110, 2001) intensiÞed accountability efforts by mandating sanctions for schools and districts that do not meet academic performance standards. Two key positions of NCLB have inßuenced the practice of school psychology in particular: stronger accountability for results and proven educational methods. School psychologists will need to examine professional functions and quality of services, not only by ratios of professionals to students or other broad indicators such as number of students tested or "served" (cf., Goodman & Young, 2006). Future efforts to examine the impact of the support services will be guided by what school psychologists do and to what effect.In school psychology, there likewise has been an increasing focus on accountability and on promoting services that have a demonstrated positive impact on students. Training standards of the National Association of School Psychologists (NASP, 2000b) reßect the growing focus on accountability in accreditation and training standards and include emphasis on performance-based program accountability. The NASP Guidelines for professional practice and services (NASP, 2000a) encourage school psychologists and school psychological service units to evaluate services provided and their impact on students and families. In the 2002 Conference on the Future of School Psychology, all key groups representing the profession promoted several broad themes to guide the future (Dawson et al., 2004). These themes included a focus on systems-level practices, prevention and early intervention, evidence-based interventions, and assessment linked to inter...
