My opera performance and rehearsal reports are very similar to my theatre/musical reports in that I have sections for all production departments (set/light/costumes/props/fx & other), attendance, etc. It sounds like the job you're doing for this educational tour is very different from doing an actual opera. If you do need to make reports for a full opera, I would recommend two specific things:
- add a music and orchestra notes section to your report. This is important as cuts are created and adjusted, or as musical issues arise (added fermata, bandas, maestro issues, etc), as the music is the most important part of the opera world.
- you will need to keep very careful track of the time, as your orchestra will probably be union even if the rest of the house is not. So you should add timings for: first tune, downbeat, end of Act I/begin intermission, end of intermission/begin Act II, tune 2, second downbeat, end of opera, final curtain. There are many complicated rules and regulations for the orchestra, and usually their clock begins when they tune and ends on the final cutoff. So you must track this very carefully in case the is an overtime debate.
When on tour, it's usually good to add a "venue issues" section to a report.
Just curious - what sort of program are you touring?
