Our Summer 2022 Results

Transformative teacher training

"The most helpful professional development I've ever experienced."

Feedback from partners on NSSI’s summer 2023 pre-service training is glowing! 88% of teachers and 95% of administrators agreed or strongly agreed that NSSI's training prepared them for their roles this summer. One seventh-grade literature teacher shared:

NSSI's pre-service training "is the most helpful professional development I've ever experienced because it was hands-on and dynamic. I hope I get to do this again next year!"

NSSI is proudly upending expectations for what’s possible in the realm of professional development. Equipped and inspired by NSSI’s award-winning mentor teachers, they were ready to aim high—and watch their students soar.

Hear from a returning partner

"We partner with NSSI because they are 'student first.'"

One of the key factors in deciding to partner another year with NSSI was the demonstrable impact of the program, with students making gains of 15–40% in priority grade level standards assessed through pre- and post-assessments. Moreover, students, families, and teachers continue to share with us their enthusiasm for the lessons, materials, and for the emphasis on social-emotional learning. We partner with NSSI because they are 'student first.'
