Of primary interest arc Lhc bold-faced values shown on the diagonal. These V~~UCS reflect the prcdiclivc<br />

abiliry for each composilc’s target criterion; for example, the GPA composile rcvcals a cross-validity of .289 with<br />

the GPA criterion. These diagonal values may bc compared with the four corresponding validities observed for<br />

these composites in the developmental sample: .327 for GPA; .175 for APT; .297 for NSG; and .455 for TECH.<br />

As expected, development-sample validities wcrc sBghtly higher than the corresponding cross-validities. The GPA,<br />

NSG, AFT, and TECH composites each predicted its target criterion better than any of the other composilcs.<br />

Surprisingly, lhe APT composite was a better predictor of GPA and NSG than of APT. Overall, three of t!~<br />

four. composks (CPA, APT, and NSG) were bctlcr prcdiclors of GPA and N.SG than of APT and TECH.<br />
