Rosh mesivta

The title rosh mesivta (alt. rosh metivta; ראש מתיבתא; from Jewish Babylonian Aramaic rêsh mṯivtā ריש מתיבתא‎), abbreviated as Ram (ר״מ),  is a term in Jewish education for a leading figure in an educational institution. The term has a long history, going back many centuries.

The role is comparable to a dean in a university. Just as a chancellor outranks a dean, a rosh yeshiva, when both exist, is higher.
