Q. Do women have to hear the reading of the Torah on Shabbos?
A. Mishna Berura (282: 12) quotes Magen Avrohom ruling that although women are not included in the mitzva of learning Torah, yet they are obliged to listen to the reading. However, he adds, that women are not careful in keeping this minhag.
Other Poskim assert that it is an accepted tradition that women are not obliged to listen to the Torah reading. They add that Kerias Hatorah is a Chovas Tzibur or communal obligation, to which women are usually excluded. (Aruch Hashulchan 282:11, Hisorerus Teshuva 3: 476. Piskei Teshuvos 282: 6 and others).
Horav Shlomo Miller's Shlit'a opinion is to follow the view of the Mogen Avrohom.
