Please call 1.866.706.8665 to schedule a demonstration or to begin an assessment program today.

Test Name:	Job: Inspector: Mechanical - UPDATED
Number of Questions:	138
Test Description:	The assessment for mechanical inspectors tests for a strong knowledge of math and print reading, geometric dimensioning and tolerancing, advanced inspection tools such as CMMs and optical comparators, locating principles, and a working knowledge of common manufacturing processes. This assessment also addresses common quality initiatives and process control. Test questions are based on class material from the abrasives, electrical systems, inspection, materials, metal cutting, quality, safety, shop mathematics/print reading, and workholding departments.
Test Instructions:	This online test requires uninterrupted access to a computer with an Internet connection. For math-related questions, please have paper and pencils on hand for your calculations. Textbooks, calculators, and other electronic devices are NOT allowed.

This assessment covers all these classes:
