Missi Thurman (she/her), an education consultant based in Portland, Oregon, champions teacher teamwork and has a nerd-level passion for data-driven instruction. Her company, Educational Excellence, advocates for students and strives to help educators meet their increasingly diverse needs. She cherishes time with her husband and the ever-growing number of kids who join their home. Missi Thurman (she/her) wrote this book for her students, past and present. Today, she works with school districts and teaches them about the exciting science of learning. Every day, Missi observes educators working hard to plan thoughtfully and use data to make better decisions for their kids, but there are some barriers. The test-taking environment doesn't support every kid's ability to demonstrate what they know-some kids find it hard to try their best, and others worry too much about being perfect. Missi wrote this book to offer kids a sneak peek into the "secret" world of what teachers do before and after school with their students' work! Her hope is that it reduces the mysterious testing scaries and helps kids, their grownups, and their teachers become better partners in helping every student succeed.
