SHOP EMPLOYEES TO TAKE AND PASS
ATRAВ’S CERTIFICATION TESTS
PREPARATORY TEST Instructions
REVIEW AND RESEARCH
Give out the preparatory tests as soon as possible in order that the technicians have enough
time to review and research each question.
tests.
All the questions listed will be on the actual
ATRA is no longer providing the answers to the prep test questions.
We believe an
ATRA Certified Technician should either already know the answers or know how to find the
answer using whatever resources are available.
Examples of resources:
Technical Manuals,
Seminar books, ATRA Online, Bulletins, HelpLine, etc.
Technicians may discuss the questions and use the glossary of definitions to make clear any
words that are unfamiliar.
There are two types of questions in these Preparatory Tests:
or False and Multiple Choice.
True
These are the same type of questions you will find on the actu-
al Certification Tests.
TAKING THE PREPARATORY TESTS:
After researching the questions, it's a good idea to do a practice test.
This way, the pace of
the actual Certification tests will be familiar.
Apprx. time needed to test:
Rebuilder
R & R
Diagnostician
1 hour
45 minutes
1 hour
The answers may be circled directly on in the booklet or written on a separate sheet of paper.
The use of a calculator is allowed where necessary.
REVIEWING PREPARATORY TESTS:
When the tests are completed, compare the answers from several technicians.
Where there
are descrepancies, we recommend that you discuss those questions or problems as a group.
This will help reinforce correct answers and the best way to find them.
ATRA works hard to provide testing that has as much value as possible... an ongoing effort
that takes many things into consideration, including feedback from the industry.
We appreci-
ate your input and would like to say В“Thank You!В”
