Something to consider:

3 that aged women likewise be reverent in demeanor, not slanderers nor enslaved to much wine, teachers of that which is good; 4 that they may train the young women to love their husbands, to love their children, 5 to be sober-minded, chaste, workers at home, kind, being in subjection to their own husbands, that the word of God be not blasphemed:

I think the use of "aged" women and "train" in this translation (ASV) is due to the reticence to use the term "elder" and "teach".

Still, Paul is charging these aged women to teach or train the younger women.

So my question is this. Paul gives explicit criteria for selecting elders, deacons and even widows who are to be enrolled in church care. Where does he give the criteria for selecting these elder women who are to train others if it is not the same section in Timothy where he explains how to select elders?
