What rules do I coach to with U13 to U19 school and junior teams in South Africa? Match times, replacements, front rows, scrums, U13 lineouts, tackle height, playing up, BokSmart and concussion.
The World Rugby Laws of the Game apply to all junior rugby in South Africa, with these SA Rugby additions:
| Age group | What applies on top of the World Rugby laws |
|---|---|
| U13 (primary school) | SA Rugby Primary School Law Variations 2025: lineouts, mauls, scrums, barefoot play, size 4 ball, 5-minute yellow cards, rolling replacements |
| U14 to U19 (high school) | World Rugby's Under 19 law variations |
| All ages | SA Rugby Scrum Law Modifications (January 2026), the playing time and replacements directive (February 2025), the lowered tackle height laws for school and club rugby, the School Age-Banding Regulations (January 2026), the Concussion Regulations and the BokSmart regulations |
Competition rules can add to these, for example which replacement option is used.
SA Rugby's February 2025 playing-time directive for school rugby:
| Age group | Match length | Sin bin | Half-time |
|---|---|---|---|
| U13 | 2 × 25 min running time | 5 min running time | 5 min |
| U14 and U15 | 2 × 25 min playing time | 5 min playing time | up to 5 min |
| U16 | 2 × 30 min playing time | 5 min playing time | up to 5 min |
| High school 1st team | no more than 70 min playing time | 10 min playing time | up to 10 min |
SA Rugby's February 2025 replacements format for high and primary school rugby:
Squad minimum: a squad of 23 must include 6 front-row players, and you must be able to replace the loosehead prop, hooker and tighthead prop at the first time of asking.
Option 1 (if both schools agree beforehand)
Option 2 (league matches, or where the schools don't agree)
Competition rules can set which option applies. Any other deviation needs prior approval from the SA Rugby Community Referee Manager.
SA Rugby's February 2025 directive on high and primary school matches says that when scrums become uncontested, the team that caused it plays short, using the Uncontested Scrum Reduction Table:
Uncontested scrums are still played with eight players a side.
The reduction table does not apply to primary school rugby. The directive notes that the BokSmart Rugby Safety Programme always applies.
SA Rugby's Scrum Law Modifications (updated January 2026):
| U10 to U16 (incl. provincial school teams) | U18 and U19 (school, club, provincial, national) | |
|---|---|---|
| Calls | Crouch, Bind, Scrum | Crouch, Bind, Set |
| Engagement | Passive, pre-bound, no hit | Active, with a reduced hit |
| Ball in | On the "Scrum" call | When the scrum is square and stationary, with no signal from the referee |
| Push | Max 1.5 m, then the contest stops | Max 1.5 m, then the contest stops |
| Turnover scrum | No | No |
At all these ages:
U13 is primary school rugby, so SA Rugby's 2025 Primary School Law Variations apply on top of the World Rugby laws:
Lineout
Maul
Scrum
Other
SA Rugby's lowered tackle-height laws have applied to all school and club rugby since 2024. They do not apply to senior professional rugby.
Tackler (open play)
Ball carrier (open play)
At U13, the Primary School Law Variations also set the tackle height below the base of the sternum and above the knees (penalty kick) and ban the sling tackle.
SA Rugby's School Rugby Age-Banding Regulations (January 2026) set the age group by the age a player turns during the calendar year. Nobody may play in an age group if they are older than its limit, so playing down is not allowed.
U13 (primary school): two-year band, no exceptions. A player may be at most two years younger than the oldest age in the group, so U13 players are turning 12 or 13 that year.
U14 to U18 (high school): two-year band, extendable to three years for an individual player. For example, a player turning 16 could play U18, but only if:
The coach must answer "Yes" to every question on physical development, skill, experience and safety risk, and must have completed the BokSmart pre-participation screening with the player.
The three-year band is the absolute limit. A whole team may not enter an older age group's league.
SA Rugby treats the front row, especially hooker, as the highest-risk position for catastrophic neck injury. A younger high-school player may not train or play in a higher age group at loosehead, hooker or tighthead until Schedules A and B (and Schedule C where it applies) have been accepted by the provincial union.
Schedule B asks the World Rugby Level 2 coach, with the player and parents, about:
Schedule C applies where the player did not play in the front row last year, did not play a full season there, or lacks specialised front-row coaching or conditioning in the last two years. The coach must confirm that, in the 8 weeks before, the player has done position-specific neck strengthening, progressive live scrum training (e.g. 1v1 up to 8v8) and scrum-specific conditioning.
Apart from the answers that send a player to Schedule C, any "No" on Schedule B, or a "Yes" to missing games with a significant head, neck or spine injury, means the player should not be cleared. On Schedule C, any "No" means the same.
Under SA Rugby's School Rugby Age-Banding Regulations (January 2026), school U19 is the only age group with an automatic three-year age band:
Schools are encouraged to run an U16 team (or U17 in schools playing U19 leagues), so that younger players do not need to play U18 or U19.
Under SA Rugby's regulations for the BokSmart Rugby Safety Programme:
If you are not compliant:
For players playing up an age group, the coach who assesses them must also hold a World Rugby Level 2 coaching qualification and have active BokSmart certification.
SA Rugby's Concussion Regulations (updated December 2025) apply to all players, and ask for extra caution with players under 19:
The off-field Head Injury Assessment (HIA) is not used in school or junior rugby. It is only for World Rugby-approved elite adult competitions.
