Scott Gordon, founder and chief executive of the sprawling 22-year-old Mastery Charter network, will leave the system at the end of the 2022-23 school year.

Gordon’s decision to step down comes as the organization prepares to engage in a new strategic planning process. It’s someone else’s turn to help shape what comes next, he said.

“I’ve been thinking about sustainability of Mastery and our ongoing work and evolution,” Gordon said. “I’m not burnt out, I’m not tired. I just had a milestone birthday and I wanted to try out something else before I retire.”
