This document outlines requirements for evaluating schoolwide projects funded under Title I Chapter 1 of the Elementary and Secondary Education Act, 1975. The following school-level requirements must be met on a school by school basis: (1) demonstrate the aggregate achievement gains of all disadvantaged students in grades 2-12; (2) examine student-level achievement gains and modify the program accordingly; (3) monitor and assess the attainment of desired outcomes at all grade levels; and (4) conduct an annual review. District-level requirements include examining the academic achievement of students in the regular program and conducting a sustained effects study every three years. A summative evaluation must be conducted at the end of the third project year comparing the achievement gains attained in grades 2-12 by the schoolwide project to the achievement gains of either other disadvantaged students in the district that same year, or to the achievement gains of disadvantaged students in the same school for the 3 years prior to the initiation of the project. The following materials are appended: (1) a guide for determining project years; (2) two examples of determining "comparable data" for evaluation purposes; (3) two forms for defining the basis of the achievement gain comparison; (4) an example of the calculation of average achievement gains; and (5) the requirements for demonstrating desired outcomes.
