Depth jumps, single-leg
From a 12-18 inch box, step off, land on one leg, immediately jump up off the same leg. 3 sets of 4-6 per leg, full rest. Trains stretch-shortening cycle, which is what high jump takeoff demands.
High jump height correlates strongly with vertical jump, and vertical jump correlates strongly with plyometric ability. Most HS high jumpers under-do plyo or do it as gym filler. Below: the plyos that actually move bar clearance, with the loading and sequencing that lets them stick.

Two-leg jumps onto a tall box. 3 sets of 5. Less for raw height of the box, more for clean takeoff and landing pattern. Build height progressively over weeks.
20-30m of alternating bounds, focus on horizontal force and clean landings. 3-5 reps. Builds the approach-to-takeoff force the flop requires.
Plyo work shows up in jumping numbers but also in takeoff power on the runway. Film a high jump attempt every 4-6 weeks. AI compares takeoff knee height, hip rise, and trail-leg snap. If the plyo is working, all three improve.
