Caveat: There is no case law on this issue.
This issue comes up periodically. As noted, there is no case law on the issue of whether school sponsored activities conducted off-campus render such locations off limits to CHLs. However, it is my opinion that TPC §46.03(a)(1) makes it clear that the "grounds" or "building[s]" where the school sponsored activities are conducted must be owned by the school. There are at least two justifications for this position. First, everything in §46.03(a)(1) deals with school property. This is shown by the phrase "of a school or educational institution" and by reference to "a passenger transportation vehicle of a school or educational institution." If a teacher put her class on a city buss to go to the library, the activity would be school sponsored, but the buss would not be "a passenger transportation vehicle of a school," thus it would not be off limits to CHLs.
More importantly, all of the prohibitions can be waived by a school, as evidenced by the provision "unless pursuant to written regulation or written authorization of the institution." Schools clearly do not have the authority to authorize the carrying of firearms on property they do not own, so they would not be able to authorize anyone to carry a gun into a public library. Nor would a school have the authority to allow someone to carry a gun into a private restaurant, if the school sponsored activity included lunch at such a location. The only way this closing phrase can be meaningful is by reading §46.03(a)(1) to apply only to property owned by the school. The rules of statutory construction require that statutes be read in such as way as to give meaning to every provision, unless this is impossible. Every provision in TPC §46.03(a)(1) can be harmonized, but only by applying it solely to property owned by the school.
