SAT Validity Coefficients

Give me some information about SAT Validity Across Colleges?

You want information about SAT Validity Across Colleges so following is its informations:

Traditionally, the validity of a test has been judged according
to how well the test performs in a particular situation or
institution, as evidenced by data collected solely in that
situation without regard to data collected in other similar situations. This emphasis on the need for local validation was reinforced by the apparent variation in validity among situations or institutions. It became increasingly apparent, however, that much of the observed variation was a result of statistical artifacts, such as sampling error and differences among sites in the range of test scores and in the reliability of the criterion. Just how much of this apparent variation among sites could be explained (or was generalizable) by these purely statistical factors, and how much might result from more substantive differences among situations was open to empirical study. A number of empirical methods were developed and applied in numerous situations, mostly employment settings, and generally the findings have supported the hypothesis of validity generalization.

Rest of information is available in attached pdf file. I am providing you the same and you are free to download it.

I don’t understand what should I write in this question.
