This shows the teaching experience and the percentage of beginning teachers as reported by the state. Although experience alone is not an indicator of teacher effectiveness, schools with few experienced teachers or a high percentage of beginning teachers may face difficulties. This is because teachers with limited experience may be less skilled at managing the challenges of classroom instruction.
Conversely, a high percentage of experienced teachers or a low percentage of first-year teachers may point toward a lack of fresh ideas and innovative teaching methods at a school. In general, the most effective schools have a combination of experienced and new teachers, and create opportunities for all teachers to learn from each other.
