You guys get it. You cannot treat students like thing-a-ma-bobs being produced on assembly line. The countless issues and stresses some kids deal with would make people cry.
Here's the truth. Some schools start out with students way behind others. Those teachers may help those students learn and grow, but if they don't meet the chosen standard, they are deemed failures.
Example: A high school junior moves into a new school. The student reads at a second grade level and can barely do basic math. The teachers and school specialists work with her tirelessly and in one year, her reading ability improves to 8th grade level and she can now do basic algebra. She takes the standardized tests and falls in the second lowest category of achievement, not reaching the expected proficiency at the junior level. By the metric of tests, she is a failure and so are her teachers. If there are enough students like her in her school (and some schools have MANY), then her whole school gets deemed a failure, too, and people that are looking from the outside will question what the hell is going on in that school or district.
However, her teachers will consider the growth that has occurred for her in just one year to be a huge success. We know the truth.
