I spent most of my time at NAIS with a great team of Maker-minded educators, each of whom has great stories about the growth and accomplishments of their program.
When I watched the faces of other teachers and school leaders in those conversations, I could see the analytic processes running very close to the surface. They were listening to these (hopefully) inspiring and entertaining stories, but only because we were too stingy or too dense to simply explain how to launch their own #makered program!
These are the three resources you absolutely  need in order to launch a #makered program:, students, faculty, and space. The precise mixture and composition of those components will dictate the starting boundaries and possibly the focus of your program.
Students are the most difficult component. Not because individual students lack interest, but because of how schools limit their options and constrain their choices.
Most K12 schools wrap all student and teacher activities around a carefully managed framework of classes, breaks, passing periods and coverage. From one viewpoint, a school’s primary resource is student hours, and the whole edifice exists to portion out students and move them smoothly from place to place. In the vast schedules that constitute those systems, very few cells are dedicated to “you know … whatever seems cool.”
Student contact hours are often set up as a zero-sum game, where established players (rightly!) view new programs as immediate opponents that could develop into existential threats. New programs don’t bluff their way through the curriculum and schedule gatekeepers with a gameplan of “just start!”
But while most schools have a carefully managed schedule, almost all of them are held together with some kludge. If you’re looking to launch a Makers program “Monday, not someday” then look for these areas. At Flint Hill we started with middle school study hall, a weird schedule-filling block that didn’t serve an academic purpose beyond “kids go here.” This year, we’ve seen great uptake Makerspace use from middle school students who are dismissed at 3p but have to wait for the 3:50p bus routes. Every school is different, but I’ve yet to find one that doesn’t have some pockets of time where the primary mandate is “have an adult in proximity to kids.” Not only are those times fundamentally unclaimed by the faculty structure, they’re often a real drag for kids as well! Providing a Makerspace alternative to those “holding pen” moments is pure upside for the students and the school.
When you’re looking to launch a K12 Makers program, start with finding a time that students can make. If you can’t find a window for it now, then you’re facing a problem that no capital campaign or architectural design team can solve.
 I’m on record as a“just start” absolutist. This list, like any attempt to three-ring binder and package the #makered process, is a compromise from that position. Please imagine that every noun and most adjectives that follow have invisible asterisks, footnotes and disclaimers.
