Well, since no one else has apparently thought of this, and I could be wrong, but I really don’t think so.
Two posters? in this discussion come in completely from left field. A teacher, has her own private tabernacle in a supply closet in her classroom that apparently contains the Holy Eucharist
The second poster is a CCD teacher who is not a Catholic

and who together with her precocious daughter" ( See I told you home schooling us would be better), are joining RCIA to grow in the faith.
Now I don’t know how things are in the rest of the world, but I have never seen a tabernacle maintained in a supply closet in a classroom, or any such place for that matter. You will however occasionally see articles on various sedevacantist and ultra traditional? web sites that allude to Tabernacles being relegated to closets, under stairways, behind toilets etc.
As far as the CCD teacher who stepped up to the plate to teach a class in a faith that she is not yet even a member of, apparently, I can only speculate. Maybe the poster is Catholic but if she is neglected to let us know that somewhat important bit of info.
However, I have seen posts in the past on this forum that I have pointed out seem to be there only to titillate, anger and otherwise disrupt things, and I honestly believe these two posts, especially the tabernacle post may definitely fall into this category.
It is also interesting to note that the tabernacle post, in all its titillating glory, is the first post by this poster as are most other posts designed for conflict.
I could be wrong, but I really I don’t think so. But as I have done before on certain other unlikely events, , if you tell me the name of the school and location and I will go there at my own expense and verify the situation and bring forth a report
Tabernacle in a classroom supply closet, gimme a break.:tsktsk:
