We have a number of daughters and all have had the Israel seminary experience. A well known posek in Flatbush told me that if I sent one daughter to Israel, then I was m’chuyav to send all who wanted to go.
One important warning to all of you reading this post: Some seminaries send out professional recruiters and tell each girl what they want to hear. One of my daughters was taken in by such a recruiter and when she arrived at the seminary, it was nothing like the the recruiters’s pitch. My daughter realized that she had made a terrible mistake. In fact, our Rav and her HS principal instructed her to leave immediately. This seminary pulled out the signed contract and refused to refund any of the $8000 down payment even though they had lots of slots still available. I was lucky that I didn’t have the full $22,000 they required before the start of the term.
Boruch Hashem for Sharfmans, who were understanding of the situation and where my daughter had a wonderful year.
