Pre Assessment

The purpose of the Pre Assessment is to help determine your current

understanding and working knowledge

The Pre Assessment will help to uncover your areas of weakness so that

appropriate training can be prescribed.

Do not take an undue amount of time trying to "figure out" the correct

answer.

Typically, you will either know the answer, or you won't.

If you do not know the answer, your natural instinct will be to "guess."

This will not help. Simply pass over the question and go on to the next

Finally, this test is not intended to either qualify or disqualify you.

It simply provides a starting point from which our training can be adjusted
