As of December 2022[update], her children all still attended Hasidic schools, including Yeshiva Mesivta Arugath Habosem in Williamsburg, Brooklyn, which she successfully sued over its education system.
Their stated mission is to ensure that all students receive the critical tools and skillsets needed for long-term personal growth and self-sufficient futures.
According to Moster, Yaffed's strategy has been "to get people from within the Hasidic community to speak up and demand a change in the current education system, where 14-year-olds spend 14 hours a day without learning a single word of English, math, science, history, or geography".
The Jerusalem Post has noted that Yaffed is one of several Jewish activist organizations around the globe, including Israel, the U.S., U.K., Canada, and Belgium, who are working towards having Hasidic yeshivas meet the general standards of secular education.
[14] Yaffed has stated that if it does not receive an adequate response from the local government, it will explore taking the matter to civil court.
[3] According to the Jewish Week, a spokesman for Attorney General Eric Schneiderman declined to comment because the issue might "be the subject of future litigation".
Yaffed argued that it was unconstitutional for the New York City and State Education Departments to credit yeshivos for the learning that takes place during the limudei kodesh portion of the school day.
[19] In January 2019, U.S. District Judge Leo Glasser has dismissed Yaffed's lawsuit over the so-called Felder amendment, ruling that the group lacks standing to sue over it.
[21] The Jewish Week reported that the major Haredi umbrella organizations, as well as some local yeshivas, have declined to comment on the issue.
The members in the Hasidic community have publicly responded to Yaffed by outlining their concerns over the effects on religious Jewish education by government intervention.
[22] Yaffed has responded by pointing out the degree to which critics agree that the lack of secular education in Hasidic schools is seriously challenging the funding argument.
