As has been pointed out, your partner can sit in court with you as a “McKenzie Friend”. There are more restrictions on this practice in the family court than in a criminal court but this practice guidance provides the details:

You will note in particular paragraph 9:
“Where proceedings are in closed court, i.e. the hearing is in chambers, is in private, or the proceedings relate to a child, the litigant is required to justify the MF’s presence in court. The presumption in favour of permitting a MF to attend such hearings, and thereby enable litigants to exercise the right to assistance, is a strong one. “
If you read all this guidance you will see that there is no blanket restriction on McKenzie friends in family proceedings but that the interests of justice must prevail.
On a wider note, the idea of a McKenzie Friend in court is to assist you, not to assist your partner with his studies. You should consider this aspect carefully before seeking permission to have an MF present.
