Also the OLSAT is screener - your district/school probably only uses it to screen. The kids that "pass" the olsat are still not considered identified as gifted - they go on to have a proper evaluation with an instrument like the WISC or SBV. It is not uncommon for a child to pass the OLSAT but then not be identified ultimately as gifted and vice versa.
Not necessarily. My district uses it as one of the 3 different ways you could qualify as Gifted.
But it is still a screener. It is just that your district is using a screener to qualify kids for the program, and not a proper IQ assessment. But that doesn't make the actual test any more than a screener. It is still a screener, regardless of how your district is using it, not an IQ test.
