Aptitude Test Study Material

APTITUDE TEST: Applicant must achieve a score of “4” or higher on the electrical industry aptitude test battery. Developed and Validated by the American Institutes for Research.

• This is a link for some examples of the Aptitude Test from the Electrical Training Alliance (formerly known at the National JATC)  http://njatcweb04.njatc.org/SamplePage . On the left hand side there will be a menu for "Preparing for the Test". You will find helpful information under all of the menu headings.
• For a comprehensive review of Algebra, the NJATC offers a Tech Math class through the University of Tennessee, click here.  This online math class is self-paced and starts off with whole numbers and works through Boolean Algebra fundamentals.  This class offers three main benefits:  

1. Successful completion of the class satisfies the math requirement for the Inside Electrician and Limited Energy Technician apprenticeships
2. It offers good preparation for the aptitude test
3. The stronger your math foundation is, the less challenging the apprenticeship curriculum will be

It is suggested to review the topics covered by a College Algebra class:
