Ryan Estrellado

Executive Consultant at South County SELPA, Educator, and Data Scientist

Background

I work at the San Diego South County SELPA, where I design solutions to help school districts build equitable systems for students with disabilities. This is my personal website, where I write about data work, education and other projects.

I’m writing a new book called The K–12 Educator’s Data Guidebook: Reimagining Practical Data Use in Schools. It will be out in late 2021 through Routledge.

Sign Up for Practical Data Activities

The book includes practical data activities for K–12 educators, but you don’t have to wait until it comes out to get them. I email a new activity every two weeks to community members. Use this link to subscribe and you’ll get your first one this Monday.
