The Effective-School Scale is presented for addressing student outcomes associated with an effective school or district for minorities. This measurement device is based on the expectations that differences in academic performance need not exist between minority and majority students, and that goals of student equality should be extended beyond basic skills to include high level academic skills. The scale consists of three parts. Two separate subscales are given first: (1) an achievement scale that allots a school points for equity or progress toward equity on standardized or criterion-referenced results; and (2) a behavioral scale that allots a school points for equity or progress toward equity on ten other student-outcome categories. Following the subscales, the effective school scale, which combines results from the two subscales, is presented. And finally, the following are briefly discussed: how the scale attempts to respond to criticisms of effectiveness identification methods; possible modifications of the scale; and limitations of the scale.
