For the 2015-16 school year I had over a hundred students take the pre-test / final exam combinations in VID1a and VID1b. 91% of my students achieved high growth from their pre-test to post-test score. Georgia defines high growth as a 45% gain between the pre-test and post-test. In Georgia’s teacher performance model a teacher is rated “exemplary” of 30% of students achieve high growth. So the 91% high growth I’m seeing is pretty amazing. Of course these numbers are coming from my own test, not an official Georgia test. But the tutorials and tests in the VID1a and VID1b websites are tightly aligned with Georgia standards. Students who complete these courses should perform well on any other test that measures understanding of the Georgia AVTF curriculum. The courses also integrate video standards from SkillsUSA, Certiport, and NOCTE. This means that students should perform well on these national credentialing tests as well.
