Question of reliabilty does not come at the time of recruitment. It is a step in test standardisation.

Test standardisation has following components:
1. Item specification/collection,
2. Mode of test administration,
3. Item analysis and item selection,
4. Reliabilty estimation,
5.Validity estimation and
6.Norm estimation.

These are technical information about any test which help a user to decide whether or not to use the test.

Hi debbie,

The following coefficients are from the publication "Testing and Assessment: an Employer's Guide to Good Practices", Employment and Training Administration, U.S. Department of Labor, 1999,

Reliability coefficients
0.90 and above, excellent
0.80 - 0.89 good
0.70 - 0.79 adequate
0.69 or less, may have limited applicability.

Validity coefficient value interpretation
0.35 and above, very beneficial
0.21 - 0.35 likely to be useful
0.11 - 0.20 depends on circumstances
0.10 or below, unlikely to be useful

Does this help?
Psychometric Tests are best used for development puropse. If you want to use them for recruitment then it is better to use the same in conjuction with interview or other data.
Regarding Psychometric Instruments...will try to answer your questions...

1) Can these tests be used for recruitment and selection purposes?

Well, According to me, Psychometrc Tests are best used for Development purpose, but if you want to use the same for Recruitment or selection then these instruments are best used as an additional tool to a battery of processes. Maybe, a support for the interview etc.

2) At what all levels ranging from technical executives and middle management to senior management ?

All levels but interpreted accordingly....for that level or future..

Psychometric assessment provides employers with an objective and unbiased measure of all things that underlies an individuals performance and fit to a role and organizational culture that can not be assessed accurately by other means. If used in conjunction with traditional recruitment methods of assessment such as resume screening, interviews, skill testing and reference checking, psychometric assessment provides important information that can be particularly helpful in making right hiring decision.
