Rabbi Jachter is a tremendous תלמיד חכם and ירא שמים whom I have spoken to multiple times. That said, I'd like to respectfully critique this article that was quoted. He is a prolific writer and mistakes are inevitable.
Firstly there is a critical flaw with the article. It fails to acknowledge that there is a recognized chiluk in Chazal which is expounded upon by the Rishonim between תורה שבעל פה and תורה שבכתב. The Chofetz Chaim wrote his heter in regards to תורה שבכתב, which although some say isn't לכתחילה, was never included כאלו מלמדה תפלות.
To write:
Even though the Chafetz Chaim endorsed the Bait Yaakov movement he did not specifically approve the teaching of Gemara to women.
Which makes it sound like he didn't say it explicitly but would've perhaps said so, is a distortion.
Undoubtedly, the Rav's prescription was more far‑reaching than that of the Chafetz Chaim and others. But the difference in magnitude should not obscure their fundamental agreement: intuitively, it is clear that the guidelines of the Talmud in Masechet Sotah were never intended for our epoch. This is not an instance of modernism, but Torah intuition.
No, there is no fundamental agreement at all. The Chafetz Chaim would not and did not allow something which the Talmud says in כמלמדה תפלות.
Rav Eliezer Waldenberg's Teshuvot Tzitz Eliezer (9:3), based on the Chafetz Chaim appears to concur with that of Rav Twersky.
That is simply not true at all.
