The pros of standardized testing include the ability to evaluate student performance consistently across different demographics, aiding in identifying areas for improvement. They also provide data that can guide instruction and curriculum development. However, the cons include the narrowing of curriculum due to teaching to the test, which may stifle creativity and critical thinking. Furthermore, standardized tests can contribute to stress among students and may not adequately reflect a student's overall abilities or potential, leading to inequities in educational assessment and opportunities for personal growth.
