This NHIE Manual was developed by the Examination Board of Professional Home Inspectors and is based on the most recent Role Delineation Study (RDS). The RDS surveyed thousands of practicing Home Inspectors to determine the types of services they provide and the components they inspect. In addition to the technical information there are 100 sample questions that mirror the National Home Inspection Exam. This Inspection Manual together with the NHIE Study Guide, prepares the new inspector for the National Home Inspection Exam and also makes a great technical reference for the experienced Home Inspector.
