Hebrew school is Jewish education focusing on topics of Jewish history, learning the Hebrew language, and finally learning their Torah Portion, in preparation for the ceremony in Judaism of entering adulthood, known as a Bar or Bat Mitzvah. Hebrew School is usually taught in dedicated classrooms at a Synagogue, under the instruction of a Hebrew teacher (who may or may not be fluent in Hebrew), and often receives support from the cantor for learning the ancient chanting of their Torah portion, and from the rabbi during their ceremony since they must read from a Torah scroll, which has no Hebrew vowels, and very close together text and minimal line spacing; making it very challenging for almost anyone to read from. Hebrew school can be either an educational regimen separate from secular education similar to the Christian Sunday school, education focusing on topics of Jewish history and learning the Hebrew language, or a primary, secondary or college level educational institution where some or all of the classes are taught in Hebrew.The first usage is more common in the United States, while the second is used elsewhere outside Israel, for example, in reference to the Colegio Hebreo Unión in Barranquilla, Colombia, or the Associated Hebrew Schools in Toronto. According to an article in the Jewish Quarterly Review entitled "The Jewish Sunday School Movement in the United States" and printed in 1900, "the exact beginning of the American Jewish Sunday schools is obscured by uncertainty and difficulty of opinion", though it is largely credited with the works of Miss Rebecca Gratz, a Philadelphia native, who sought to provide Jewish schooling to those most in need. As students received secular schooling, Miss Gratz understood the need to provide Jewish history and Jewish traditions to those most lacking a basic understanding in Jewish education. In fact, Jewish Sunday school grew largely in response to Christian Sunday school, as a means of providing proper Jewish education to students who otherwise lacked any religious grounding in Jewish traditions and history or lacked the financial means necessary to attend such a school.
