The article serves as a guide for researchers in developing evidence of validity using bivariate correlations, specifically construct validity. The authors outline the steps for calculating and interpreting bivariate correlations. Additionally, they provide an illustrative example and discuss the implications.

Notes that, very early in program planning, budgets are estimated for major program components, including evaluation. Proposes heuristic for establishing reasonable evaluation estimates in initial planning. Describes logical sources of information from which to construct such a heuristic. Recommends that, for typical programs and projects, initial…
