Standardized tests are a waste of time.... increased student achievement and teacher accountability can be more easily, and cheaply, implemented through making a passing grade an 80% instead of a 60%, portfolio documentation of post-tests for each unit showing 80% or better mastery of the standard/benchmarks being addressed, and justification of advancement rather than justification of retention. Smaller class sizes would give the teachers the individual time with the students needed to ensure adequate progress... and justify placement in special education with even smaller class sizes and specialized instruction and curriculum if the student is not passing.
That being said.... the worst thing possible is for schools to be "teaching to the test." The concept of the testing is supposed to be a random sampling of skills based directly on grade-level state standards and benchmarks... and supposedly if the teachers have been teaching the standards and benchmarks, the kids will pass. However, the tests usually are a bit above grade level in their reading levels, vocabulary, and content expectations. They usually are given long before the end of the school year, so that teachers have to make the best guess they can about which benchmarks to cover before the test, and which after. The tests make the part of the school year that "counts" to be only five months rather than nine.
If you want to be a "school leader," help with curriculum mapping to ensure that benchmark instruction is maximized toward testing expectations, while maintaining effective instruction, re-teaching, student practice, and multi-sensory activities; instruction of metacognitive strategies for test taking for the students; and instruction of general education teachers in multiple learning strategies including those best used for gifted students (compaction, acceleration, depth of information, higher-order questioning, organizational skills), special education students and lower performing regular ed students (task analysis, phonics decoding approaches at all grade levels, multi-sensory, etc.) and ELL students (modeled and guided grammar, phonics decoding approaches, cultural and idiomatic expression, etc.).
