Presidency of Young Men/Women of stake not access

In the organizations, when select class of young men/women:
- When is a member of stake presidency show list of members of class/quorum
- When is presidency of Stake Young Mem/Women NOT show list of member of class/quorum

That is correct. Only the stake presidency (with clerks and executive secretary) have access to information about youth in the stake (other than youth in their own home ward). Presumably this is to protect the privacy of the youth.

The LCR FAQ (question 1) explains that stake YM/YW presidencies are responsible for training the ward leaders and they are not responsible for the individual youth and therefore do not need that access. If they need additional information for planning purposes the stake clerk can provide the information (with the permission of the stake president).
