Leap Year

Assessing and Supporting Effective First-Year Teachers

Leap Year publication cover.

The first year is the most important year of a teacher’s career. We need to treat it that way.

Teachers who make a strong start are more likely to remain successful over time, but many schools and teacher training programs treat teachers’ first year like a warm-up. We should instead see it as a critical window of opportunity to help teachers develop essential skills and determine whether they can make a successful career teaching.

Leap Year describes the major lessons we learned from treating the first year of teaching with the care it deserves through the Assessment of Classroom Effectiveness (ACE), a multiple-measures evaluation system designed to ensure that first-year teachers in our Teaching Fellows and TNTP Academy programs meet a high standard of effectiveness.

Key Findings:

  • New teachers perform at different levels and improve at different rates.
  • Teachers’ initial performance predicts their future performance.
  • Multiple measures tend to point to the same conclusion about a teacher’s effectiveness.
  • A few specific core skills appear to be important to a first-year teacher’s success.

The report also offers recommendations for policymakers and education leaders to support effective first-year teaching, including how to make meaningful determinations about the work of first-year teachers.
