Average Vertical Jump for a 15 Year Old

Quick Answer — Male and Female Norms at 16

These ranges represent untrained or recreationally active 15 year olds with no specific jump training program. JV and varsity athletes typically sit 4 to 7 inches above these averages. At 15, the vertical jump is primarily a development baseline — which makes this the ideal time to test, identify weaknesses, and start building, since you have the most room to grow of any high school age.

What Is Good for a 15 Year Old — By Sport

If you play a sport, here is how to read your vertical against other JV and varsity athletes your age. Remember that at 15, these are development benchmarks — the point is to see where you stand and how much room you have to build, not to hit a recruiting number yet.

Why 15 Is the Ideal Age to Start Jump Training

Fifteen sits in one of the most productive windows for athletic development in a person's life. You have the combination of enough physical maturity to train seriously and enough natural development still ahead to compound your gains. An athlete who starts structured jump training at 15 has a real advantage over one who waits until 16 or 17 — the earlier you build the foundation, the higher your ceiling by senior year.

Where 15-Year-Olds Sit in Physical Development

For most males, 15 is right in the middle of the steepest natural development curve. Testosterone-driven strength and power gains are strong from 14 through 17, meaning a 15-year-old will gain vertical jump simply by getting older — training or not. This natural momentum, combined with deliberate training, produces the largest and most durable vertical jump gains of any high school age.

For females, most pubescent development is complete or nearly complete by 15, which means vertical jump gains increasingly come from deliberate training rather than natural growth. Starting structured jump training at 15 gives a female athlete the maximum runway to build toward a recruiting-level vertical by junior and senior year.

Why Starting Early Is a Competitive Advantage

The vertical jump you show at 16 and 17 — when recruiting evaluation begins — is built during the year or two before. A 15-year-old who starts training now walks into their first recruiting-relevant combine with a foundation already in place. The athlete who waits until 16 or 17 to start is trying to build that same foundation while the evaluation is already happening. Starting at 15 means arriving at the recruiting window already ahead, not scrambling to catch up.

How Much Can a 15 Year Old Improve Their Vertical?

At 15, athletes have more room for improvement than at almost any other age — natural development and training gains stack on top of each other. Here is what is realistic based on starting point and training commitment.

The biggest factor at any starting point is whether you add both strength training and plyometrics. At 15, plyometrics alone produce good results because the body responds quickly at this age, but athletes who also build squat strength see significantly larger and more durable gains. The combination of natural development plus strength plus plyometrics at 15 is the most productive training window you will get.

The Best Exercises for 15-Year-Old Athletes

At 15, most athletes have the strength foundation and connective tissue maturity to begin adding moderate-to-higher intensity plyometric work, though volume should still be managed carefully as the body is developing. Here is a program built for this stage.

• Depth jumps (3 sets of 5, twice per week) — Stepping off a 12 to 18 inch box and immediately exploding upward on landing. This higher-intensity plyometric is appropriate at 16 and produces some of the fastest reactive strength gains of any exercise.
• Squat (3–4 sets of 5–6 at moderate-heavy weight) — At 16, athletes can train closer to true strength rep ranges. Full depth, controlled descent, progressive overload week to week. This is the foundation that everything else builds on.
• Broad jumps (3 sets of 5) — Continues building horizontal power that transfers to sprint speed and first-step quickness, both of which matter heavily for recruiting evaluations.
• Single-leg box jumps (3 sets of 4 per leg) — Addresses left-right asymmetries that become more relevant as training volume increases, and builds the unilateral power most sports actually use.
• Approach jump practice (daily, 5–10 minutes) — Refining the one-step and two-step approach technique. By 16, technical efficiency in the approach can add 2 to 3 inches on its own with no fitness change.

A 15-year-old should typically train jumps 2 to 3 times per week, with recovery days between sessions. Growing bodies need more recovery than adults, and adaptation happens during rest. In the off-season, 3 sessions is productive; during the competitive season, 2 is appropriate. Prioritize quality and full recovery over volume at this age.

Comparing 15 to Other Teen Ages

The jump from 15 to 18 is one of the largest of any three-year window — most of the explosive natural development happens across exactly this span. A 15-year-old who trains seriously through these years, riding the natural development wave while adding deliberate strength and plyometric work, can reach numbers that put them well above where an untrained peer will ever get. This is why starting at 15 matters so much.
