At the High School of Language and Innovation, part of our teacher hiring process is having the candidate deliver a 15-minute demonstration lesson (a “demo”) in front of one of our classes. A candidate can nail an interview but the demo is often the most telling part of the process because we see what the person would be like in front of real students.
I wrote in an earlier blog about the comparatively low number of Latino boys in my school who are graduating on time. When I expressed this concern to my leadership consultants Ariel and Shya Kane, they suggested that in every demo lesson, we include a significant number of Latino boys and take special note of how the teacher engages those boys. This suggestion has been invaluable– rather than looking narrowly for a certain “type” of candidate, we’ve shifted to simply seeing who our students become in front of that candidate.
Since summer school classes are smaller, we have sometimes needed to add boys from other classes.

I founded the High School of Language and Innovation in 2011 with eight teachers teaching 90 students. We have now grown to 28 teachers and 350 students and have interviewed hundreds of candidates over the past seven years. In our interviews with teachers, we ask questions about topics like teamwork, teaching, taking responsibility for student results. But there is one question that tells us volumes about the candidate.
