Our position

If you have never run a soldering lesson, a classroom set of irons is a disaster waiting to happen. Start with one, scale to two, then build out. The hardware is not the bottleneck; classroom management around hot tools is.

Reputable sources worth reading before you decide. Labels reflect our honest read of each source's general stance, not direct quotes.

Any experienced teacher will say hot tools need to scale with supervision capacity, not with student count.

Why trust it: Teacher-education community consensus.

FIRST teams typically have 1-2 irons for a team of 20 kids with rotating supervised use. The ratio is about supervision, not about 'can we afford more irons.'

Why trust it: Large youth robotics program with real scaling experience.

Some CTE programs run full class sets with 25 irons and dedicated bench spacing. Works if the teacher is experienced and the room is built for it.

Why trust it: High-capacity CTE model, appropriate for high school with infrastructure.
