"OMG, you must do good on the PSSA's or the TEACHERS WILL BE NEGATIVELY AFFECTED! Make sure to fill in the bubbles completely etc etc..."
That's what my school is like. We do CATS testing.
Also, the special ed students' scores on the test are mixed in with everyone else's, while most schools in our area don't do that, so our schools' scores are some of the lowest in the area.
