The educational audit is suggested for assessing the process of inquiry for reliability and the product of inquiry for absence of bias. The inquiry auditor must review the inquiry processes to determine that they conform to norms of "good professional practice." He must review inquiry products to ensure they can be substantiated from data collected. These tasks are equivalent to establishing the dependability of an inquiry and the confirmability of its data and conclusions. The inquiry audit process is composed of the audit trail and the audit procedure. The documentation for a naturalistic audit trail incorporates a reflexive journal and a detail of procedures. The audit procedure consists of several basic steps. These include the decision to do the audit; acquisition of the inquirer's report and all portions of the audit trail; determination of documentation sufficiency; comparison of procedures to problems addressed; comparison of raw data to written narrative; description of comparison results; noting changes in methods of deployment of personnel and judgments about context and problem; noting whether inferences flow logically from data; and certification of findings in final report. An audit procedure is presented in diagram. (DWH)
