Utility Industry Math Boot Camp for the CAST Battery

The Construction And Skills Trades Selection System, CAST, is a battery of skill and ability tests designed and validated by the Edison Electric Institute, EEI, to aid in the selection of candidates across a wide variety of construction and skilled trades occupations.  This test battery measures skills and abilities that are critical for effective job performance.  There are four CAST tests:

Graphic Arithmetic, Mathematical Usage, Mechanical Concepts, Reading for Comprehension

Because of a lack of adequate math skills caused a CAST failure rate of more than 50%, the Center for Energy Workforce Development, CEWD, asked Helicon, Inc. to develop a boot camp that could be used by educational institutions to help people prepare for the CAST battery.  The following items from the Boot Camp have been made available for sale to individuals.


Student Mathematics Manual


This 352-page manual, which covers all the
mathematics topics found in the
Mathematical Usage and Graphic Arithmetic
Tests of the CAST, has over 1,500 practice
problems with answer keys for all.



Mathematical Usage Practice Tests

List of Abbreviations


Practice Test #1

There are 234 Dimensional Analysis (aka
Mathematical Usage) problems in the Student
Mathematics Manual—but for anyone who
wants to further hone her/his test-taking
skills, these Practice Tests are perfect!

There are five sets.  Each set contains
18 problems with answer sheets, answer
keys, and mathematical solutions.



List of Resources for the
Mechanical Concepts Test

The Mechanical Concepts Test of the CAST
battery assesses both mechanical compre-
hension and spatial reasoning.  This is a
all-inclusive List of recommended
readings and practice exercises from a
variety of books.
