As we go into the fall and prepare for rechartering, the district is putting a greater emphasis on making sure we have properly aligned and functioning pack and troop committees. This does not mean that all unit committees need to be of equal size.
Smaller units have fewer parents to recruit from. This means inherently smaller committees. While the Boy Scouts of America system is extremely top-heavy and presumes each individual committee member has limited responsibilities, that is not always the case. In smaller units, sometimes one committee member will be the point of contact for district or council for several different subjects.
The unit committee structure only presumes a small handful of people. Units may choose to have larger committees with greater specialization. A smaller committee means that one person may handle all membership issues. Over the course of the year, this one unit committee member may be contacted by several specialized scouters from District or Council, including Webelos-to-scout transition, spring recruitment, fall recruitment, and retention. That does not mean that the unit needs to subdivide those membership issues the same way the District does.
The Troop Committee Guidebook, Pub No. 34505B pg. 21, states,
Experience has shown that troops with committees of seven or more members work more effectively and provide better troop program support. The minimum number of committee members required is three adults ages 21 or older. If the committee is well run and active, you should have little difficulty getting others to join. But again, be sure that each member has a meaningful responsibility and is kept actively involved.
As with securing a Scoutmaster, to get qualified adults involved with your troop, you must first identify good people, select and rank the top prospects, and then use all available influence to recruit them.
This makes a lot of sense. Anyone who has been actively involved in volunteer work for an extended period of time understands that volunteering comes after family and work. This means that larger groups are needed to have more than one person have a meeting and split responsibilities. Ironically, larger committees often do better at keeping things moving because no one person is as easily overloaded.
An ideal cub pack committee would look like what is described on the BSA website.
For small Packs, it makes the most sense to make sure that you have a committee of at least five (including the chair) to handle recruiting and coordination (chair), communications (secretary), finances (treasurer), programming (committee member or a designated Den leaders), camping (committee member or different designated Den leader), etc.
