Two parallel forms of a broad-range tailored test
of verbal ability have been built. The test is appropriate
from fifth grade through graduate school.
Simulated test administrations indicate that the 25-item tailored test is at least as good as a comparable
50-item conventional test. At most ability
levels, the tailored test measures much better. An
offer is made to provide upon request item characteristic
curve parameters for 690 widely used Cooperative
Test items, in order to facilitate research.
