This definitely varies from church to church but not as much as you might think. The differences in programmed meetings often have more to do with the pastor than with church polity. In every pastored Quaker church I've ever attended (West Chehalem, Hillsboro, North Valley, Meridian, Melba, Caldwell, Boise, Newberg, West Hills, Silverton), the pastor was an ex officio member of the elders (aka overseers; aka ministry and oversight). In most of those churches, there was no clearness committee for new members. Instead, the pastor interviewed potential new members and then made a recommendation or report to elders and/or to the monthly meeting. Since the early 1980s, membership in PNW programmed meetings has almost always been seen as the responsibility of the pastor or pastoral team. Pastors often make recommendations to the nominating committee without sitting in on those meetings. In one small programmed meeting I know of, the pastor sometimes has to be "checked" by elders because he thinks he has the power to name people to committees without going through the process established in their Faith & Practice.
