These regulators are getting out of hand--if a service qualifies it qualifies. It is industry standard to combine board membership activities because it is considered an on going commitment, but not required. If a bank were to issue multiple grants to a nonprofit--we wouldn't deny the least valued loans because we already lent to an organization. Under the most recent Q&As an examiner is not to consider only the quantitative factors, but the qualitative factors of activities. Multiple employees teaching the same class allows for the activity to be more responsive. You're unfortunately going to have to be on the defensive with this examiner and ask her to demonstrate where in the regulation it states that service activities must be combined, or denied if made to the same school or students. Not only that, but what if multiple people are teaching different classes at the same school on the same day. More people benefited from that activity, but if we were forced to deny those other records or combine them it wouldn't demonstrate how qualitative the activity was.
