I think this is a good point.

However, if we maintain the standardized testing, I would say also reward teachers who improve students from say 95% to 99% or keep them scoring 99%.

When I was in school, I would consistently score 98-99% on standardized tests. One of my teachers was forced by the principal of the school to apologize to my parents for not improving my scores.

Yes most of these are just tweaks. "How much reward for a X% increase?" "How much reward for an increase from Y% to Z%" etc. This can easily be adapted as time goes.
