Survey Validity & Reliability Study

In Spring 2012, AdvancED conducted a formal validity and reliability study of the perception surveys  developed by  Lorraine A. Ozar, Ph.D. (Chair), Loyola University Chicago; Susan Ferguson, Ed.D. University of Dayton; Adam Krueckeberg, MBA/MA Pastoral Ministry, Boston College; Kathleen Schwartz, Ed.D., Diocese of Venice FL; Patricia Weitzel-O’Neill, Ph.D., Boston College, with support from AdvancED.   The study confirmed that schools can confidently use the surveys to gather general shared perceptions of various stakeholders in regard to the school’s general adherence to the Standards and the Defining Characteristics.    Reliability estimates of a composite score computed by averaging over respondents and items within the same school indicated exceptionally high reliability (i.e., very minimal measurement error) for most constructs.
