The Model IV Intervention is one of four models that provide technical assistance to Virginia school divisions and that are now being tested by VDOE under the PA+SS project. The Model IV Intervention differs from Models I, II, and III because it is directed from the school division central office, includes a central office school improvement specialist and is designed around the concept of building school capac-ity through collaborative work between the school principals and school improvement specialists hired under the PA+SS project to assist with the Model IV implementation. The model focuses school improvement planning on specific skills, concepts, and content in each of the Petersburg City Schools accredited with warning. A warning status indicates the school has not fully met state accreditation stan-dards, particularly those related to student achievement. Because all Petersburg City Schools are accredited with warning, the central office specialist is assigned to work with the central administration for up to 20 hours each week, although over time this role has expanded to 4 days per week. The main goal of the intervention is to improve stu-dent achievement to levels that ensure full accreditation in compliance with the state accountability model. Short-term goals include ensuring that (1) data are used to make sound instructional decisions at both the individual school and district level, (2) school and district faculty have the skills needed to develop a strategic plan for improvement based on these data, and (3) structures are in place and used to monitor that the strategic plan is implemented with fidelity.
