The Inspection Certification Program document outlines the certification program elements and intent. 
Full time Inspectors are required to pass the General Inspector Certification exam and required discipline certifications as needed. Some aspects of the program are tailored for convenience, such as not requiring a certified Inspector to hold a Bridge Inspection Certification until he/she is expect to inspect bridge construction.
Training is available for each of the certifications; however, an Inspector may choose to challenge the exam. Training courses are scheduled between November 1 and April 30. Class schedules and registration information are provided below.
