Which document is NOT required to prove player eligibility?

To determine which document is not required to prove player eligibility, we need to examine the purpose and necessity of each option within the context of player registration and eligibility verification.

A birth certificate is critical as it provides official proof of a player's date of birth, which is essential in ensuring that the player meets the age requirements for their respective category in competitions.

A passport serves a similar purpose by confirming the player's identity and nationality, which is important for international play and participant eligibility across borders.

Passport-size photographs are often required for identification and documentation purposes, ensuring that the player can be recognized and verified in official records and during competitions.

In contrast, a school transcript, while informative about a player's educational status and potentially relevant for eligibility in certain contexts, is generally not a mandatory requirement for proving player eligibility in most competitive leagues and associations. This is why the school transcript is considered less critical than the other documents listed for proving player eligibility.
