Yes to PPs. A 25-minute CogAT is definitely a screener (probably the 3-subtest version). Actually, it's expected to take 39 minutes, but maybe she worked more quickly. And yes, students not unusually score differently on the WISC-V and the CogAT, even when it's the comprehensive CogAT. Young students in particular can generate unstable scores. Was it the computer-administered CogAT? Sometimes that affects young students negatively, especially those who haven't previously had much standardized testing experience.
