Q. See question 9 above. Can a woman be trained and after learning well the Halachot of Mezuza be able to check and certify the Kashruth of a Mezuza?
A. Horav Shlomo Miller’s Shlit’a opinion is that a woman should not engage in checking and declaring a mezuza certified kosher, even if she was trained and learned well the Halachot of Mezuza, since she would be rendering Psakim and ruling Halacha.
