Your data will never be the same. No more guessing. No more misjudgments. No more competitive culture that undermines the collaborative culture you’re trying to build.

Split testing is:

  • Isolating classroom variables that impact student learning.
  • Comparing a teacher to herself.
  • Cyclical.
  • A continuous process of reflection and growth.
  • Also known as A/B testing.
  • Based on “before” and “after” data – growth-oriented.

Split testing is not:

  • Using non-comparable student groups.
  • Muddied with unknown variables.
  • Competitive and combative.
  • Evaluative.

Split testing will be the trend in data analysis for schools in the next five years. It will revolutionize your professional learning and academic growth in your school. I fully recommend starting split testing now.
