Papal Decree Regarding the Education of Catholic Children?

The following question has been motivated by the post https://christianity.stackexchange.com/questions/94736/what-teachings-do-all-catholic-schools-share I recall having read something many years ago specifying that parents have the responsibility to provide their children with a Catholic education (i.e., enroll them in a Catholic school for years ago, home school was not legally an option); and, if for some reason they were not able to, and were intending to send them to a public school, a special dispensation needed to be obtained from their bishop. As far as I can recollect, the above is the gist of what I read; though, I have often tried to find this again in writing and have been unable to. Question: **Does anyone know if such a promulgation has ever been made? Since it refers to *all* Catholic parents, I imagine that what I had read was referring to something included in a papal decree.**
