I had the honour to "say" the oath in our graduation ceremony, since I was 1st in the rank. Now, I want to include that in my CV that information. What verb should I use?

"Told the oath in graduation ceremony", is what I thought, but the verb does not sound right, does it?

In the dictionary, I found the verb take, which is not what I want, because every student actually takes the oath, but only the top one "tells" it.

Recite and administer are best (IMHO) words suggested in the comments. Either you may argue for one of them over the other, or suggest something else.
