Should you start a soldering program with a full class set?
Our position, and the 'everyone in parallel' counterpoint.
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.
Classroom-management literature
Broadly agreesAny experienced teacher will say hot tools need to scale with supervision capacity, not with student count.
FIRST Robotics mentorship model
Broadly agreesFIRST 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.'
Parallel-workflow advocates
Pushes backSome 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.
