Industrial Instrumentation
Test Development and Supporting Organizations

Development of the program was initiated in 1985 with technical guidance from the ISA (then the Instrument Society of America).

Through a practice analysis, a volunteer panel of experts identified industrial instrumentation engineering technicians' job tasks and responsibilities and categorized them into work elements. Volunteers then submitted and reviewed examination questions for each of the work elements. The Instrument Society of America solicited industrial instrumentation technicians with varying levels of experience to participate in a field test of the exam questions.

This program became operational in 1988. Technical guidance is currently provided by ISA: the Instrumentation, Systems, and Automation Society and its members, and by individual engineering technicians.
