Rambam, Mishneh Torah, Laws of Talmud Torah 2:5
עשרים וחמשה תינוקות למדים אצל מלמד אחד, היו יותר על עשרים וחמשה עד ארבעים מושיבין עמו אחר לסייעו בלימודם, היו יותר על ארבעים מעמידין להם שני מלמדי תינוקות.
25 children learn with one teacher. If there are between 25 and 40, they place another person with the teacher to assist him in educating them. If there are more than 40, they appoint for them two teachers. [translation by Lisa Exler]
