A great amount of effort is being expended in the Javelopment<br />

of the ECL screening tests in order to obtain the highest reliability<br />

and validity for each form of the tests. For test reliability, both<br />

the internal item consistency and the alternate-form reliability are<br />

carefully checked. For test validity, we check the content validity,<br />

construct validity, and predictive validity. The reliability index<br />

and the construct validity coefficient of each of the different forms<br />

have been kept above .90. The coefficients of the predictive validity<br />

have shown above .65. X11 of these cutoffs are considered high<br />

st .mdards in test validation. For an example of statistical data,<br />

please refer to handout, Table 1.<br />

We have also correlated the ECL tests against the Test of English<br />

As X Foreign Language (TOEFL) tests, the University of Michigan<br />

.<br />

language proficiency tests, and the American University language tests.<br />

Pretesting has also been conducted at San Francisco State College, the<br />

University of Texas, Tesas AfJl, and the University of Minnesota. The<br />

,results were around .80, indicating a high correlation with their<br />

criterion tests of English proficiency.<br />

The SET tests do net use converted standard scores as do the ECL<br />

tests. They arc designed to use percentage scores with pass/fail<br />

cutoff scores. For the 6500, 6700, 6900, 7200, and 7400 SET tests, we<br />

have used minus one standard deviation as the cutoff point since these ’<br />

are proficiency type tests.
