The title rosh mesivta (alt.
rosh metivta;[1] Hebrew: ראש מתיבתא; from Jewish Babylonian Aramaic rêsh mṯivtā ריש מתיבתא), abbreviated as Ram (ר״מ),[2][3] is a term in Jewish education for the person in charge of a Jewish all-boys high school, as "Rosh" in Hebrew means "Head", and "Mesivta" is the accepted term for a Jewish all-boys high school.
The term has a long history, going back many centuries.
[4] The role is comparable to a dean in a university.
[5] Just as a chancellor outranks a dean,[6] a rosh yeshiva, when both exist, is higher.
