How Many Players Should Trial for Each Netball Team? A Squad-Size Guide

The Goldilocks problem

Run trials with too few players and you don't have a real comparison — you're effectively confirming the team you already had in mind. Run them with too many and selectors can't possibly assess everyone fairly inside a few hours.

The right number depends on how many teams you're picking, how many courts you have, and how long your trial runs. Here's a framework.

Start with the number of spots, then multiply

The simplest rule of thumb: trial 1.5 to 2 times the number of total spots you're filling.

If you're picking one team of 10, trial 15–20 players. If you're picking three teams of 10 (so 30 spots total), trial 45–60. Below 1.5x and you're not really competing for spots; above 2x and the day becomes unwieldy.

Adjust by age group

Younger age groups need a slightly higher multiplier because individual performance varies more day-to-day. A nervous 11-year-old can have a quiet first game and bounce back; an experienced 16-year-old usually performs to type within 20 minutes.

A practical guide:

• Ages 9–12: 2x spots, with multiple games per player to smooth out nerves
• Ages 13–15: 1.75x spots
• Ages 16+: 1.5x spots, often supplemented by known recent form

Court-time per player

The other constraint is total minutes on court. A useful target: every trialist gets at least 30 minutes of court time across at least three different game segments. Below this threshold, selectors can't assess anyone reliably and the data is dominated by who happened to play well in their one good game.

Working backwards from this:

• 1 court, 4-hour trial → roughly 24 player-spots × 30 min = 720 player-minutes available → max ~24 trialists
• 2 courts, 4-hour trial → ~48 trialists max
• 3 courts, 4-hour trial → ~72 trialists max

These are upper bounds. In practice, transitions, briefings, and breaks reduce effective court time by 20-30%.

Position coverage matters more than headcount

Even if your headcount is right, you'll have a problem if you only attract three goal shooters. Before publishing trial registration, ask players to indicate their preferred and secondary positions. If you're short on a position, recruit specifically for it rather than letting numbers fall where they may.

GameStats trials shows you a position-coverage breakdown as players register, so you can see imbalances before trial day rather than at it.

Should you cut after the first round?

For larger trials, a two-round structure can help: an open first round with everyone, then a callback round with the top 60-70%. This lets you observe more players while still giving the strongest candidates a longer, deeper look.

The downside is logistical — two days of trials means more selector commitment and more parent disruption. For most grassroots clubs, a single well-structured day works better than two stretched-thin ones.

What about pre-selected players?

Some clubs effectively pre-select returning A-team players and only "trial" for the borderline spots. This is sometimes the right call (development squads, state-league pathway teams) and sometimes a recipe for resentment.

If you're going to do it, be transparent. Say "places 1-7 are confirmed from last season's squad; we're trialling for the remaining 3 spots." Players and parents can accept that. They cannot accept being told a trial is open when it isn't.

Capacity vs quality

A final point. It's tempting to invite more players because you don't want to turn anyone away — especially in clubs trying to grow participation. But a trial that gives every player a real shot is worth more than one that gives every player a token appearance.

If you're routinely over your capacity, the answer isn't to squeeze more in. It's to add a court, extend the day, or run a separate development trial. Players remember whether they felt fairly assessed long after they've forgotten what spot they got.

The bottom line

Right-sizing trials is mostly arithmetic: spots × multiplier, capped by available court-time. Get that ratio in the 1.5x–2x range and you have a real competition with assessable data. If you want the registration tracking and rotation generation handled for you, that's exactly what GameStats trials does — and the resulting selections feed straight into the stats platform for the season ahead.
