I wonder if in order to get a recommended score and how long the score is good for depends on the company that one is testing for?

When I took my test, I Made sure I was answering correct. I finished the Mechanical, 13 of the assembly, 30 of the reading, 9 or 10 of the math. It wasn't the best but it passed.

And the HR testing facilitator told me that the results Will be good forever unless EEI changes anything in the testing.
The position I was testing for was an Assistant Unit Operator Apprentice.
thanks to everyone for all the great posts, it was nice to be able to get other ways to attack this test. I didn't pass this the first time I took it but the second time got it.
I really liked the Barron's mechanical and spatial study book. It had the same assembly, and "line" test to study for the test. And some prayer to God never hurt either.
I didn't get the position, they gave it to a guy who worked at the plant before. But I am hopeful for the next opening.
