Mesivta (also metivta; Hebrew: מתיבתא, "academy") is an Orthodox Jewish yeshiva high school for boys. The term is commonly used in the United States to describe a yeshiva that emphasizes Talmudic studies for boys in grades 9 through 11 or 12; alternately, it refers to the religious studies track in a yeshiva high school that offers both religious and secular studies. The comparable term in Israel is yeshiva ketana (Hebrew: ישיבה קטנה, lit. "small yeshiva"). After graduation from a mesivta, students progress to a beis medrash, or undergraduate-level, yeshiva program.
In practice, yeshivas that call themselves mesivtas are usually a combination of mesivta (high-school) and beis medrash (post-high-school) programs. Students in the beis medrash program are often called upon to mentor those in the mesivta.
 In Talmudic and Geonic eras
The term metivta first appears in the Talmud, where it refers to a yeshiva of Talmudic sages. Rav learned in the metivta in Tzippori under Judah ha-Nasi, his son, and grandson. Under the leadership of Rav and Shmuel, the Talmudic Academy of Sura during the Babylonian Exile was called a sidra, but under Rav Huna, the second dean of the Academy of Sura, the yeshiva began to be called a metivta and Huna was the first to hold the title of resh metivta (corresponding to rosh yeshiva). According to Graetz, the metivta convened in certain months of the year. Metivta frameworks continued to operate throughout the era of the Geonim, a period of approximately 1,000 years.
 Modern-day concept
Rabbi Shraga Feivel Mendlowitz introduced the concept of a mesivta as a Talmudic studies program for boys aged 14 and older in New York in 1926. Until that time, religious boys attended Talmud Torah (elementary school) until their bar mitzvah and then went on to public high school and college, where their level of Torah observance and commitment were sorely tested. The only post-bar mitzvah religious education available at the time was at Yeshivat Rabbeinu Yitzchak Elchonon, which prepared students for a career in the rabbinate. When Rabbi Mendlowitz, who had begun teaching at the Yeshiva Torah Vodaas elementary school in 1923, suggested the innovation, he was met with widespread resistance. An editorial in the Yiddish Morgen Journal stated:
Just as the Reform have a rabbinical Seminary in Cincinnati, and the Conservative have the Solomon Schechter Seminary in New York, so should Yeshivas Rabbeinu Yitzchak Elchonon suffice [to produce Orthodox rabbis].
With the support of three Torah Vodaas board members – Binyomin Wilhelm, Ben Zion Weberman, and Abraham Lewin – Rabbi Mendlowitz successfully opened Mesivta Torah Vodaas in its own building in Williamsburg, Brooklyn, in September 1926. The mesivta opened with four classes of post-bar mitzvah students and 11 students in the advanced, beis medrash program. The mesivta went on to graduate generations of students who became Torah scholars and leaders in the American Jewish world.
Rabbi Mendlowitz also influenced the administration at Yeshivas Chaim Berlin to expand beyond eighth grade and open a mesivta as well. Mesivta Rabbi Chaim Berlin opened in the 1930s. Other mesivtas founded in the 1930s and 1940s were Mesivta Tifereth Jerusalem, Kaminetzer Mesivta of Boro Park, and Rabbi Jacob Joseph School. In the 1950s, the latter four mesivtas had their own basketball league.
In 1937 Rabbi Mendlowitz founded Camp Mesivta, the first yeshiva summer camp in America, in Ferndale, New York. This became the summer camp of choice for thousands of students from other yeshivas and a prototype for yeshiva learning camps in later decades. Rabbi Mendlowitz instituted the practice of inviting Gedolim to visit the camp for a few days or a few weeks, giving campers the experience of seeing Torah greats in action. The Gedolim who regularly stayed at Camp Mesivta included Rabbi Yaakov Kamenetsky, Rabbi Shlomo Heiman, Rabbi Moshe Feinstein, and Rabbi Avraham Kalmanowitz. Camp Mesivta operated until the early 1960s; in 1966, it was succeeded by Camp Ohr Shraga-Beis Medrash LeTorah in Greenfield Park, New York, headed by Rabbi Zelik Epstein and Rabbi Nesanel Quinn.
 Mesivtas today
Today mesivtas are located in cities throughout the United States that have a sizable Orthodox Jewish population. Since the 1980s, the number of mesivtas in the New York/New Jersey area has mushroomed. Whereas before there were at most a handful of schools to choose from, today every city with a religious Jewish population and nearly every township has a yeshiva high school. Because of the proliferation, mesivtas have developed reputations that reflect the academic level of their students. There are schools for metzuyanim (top learners), schools for average students, and schools for students with "serious scholastic and/or yirat shamayim (religious belief) challenges". Some mesivtas operate different "tracks" to satisfy a diverse student body.
Mesivtas, like yeshivas, do not follow the public education schedule of terms and vacations, but organize the school year according to the Jewish calendar. School is in recess during Jewish holidays, and the term ends in the month of Av, the traditional break for yeshivas since the days of the Talmud. There is also a dress code: whereas in elementary school, boys wear casual clothes to school, upon entering mesivta, they are expected to dress in dark suits and white shirts.
