The Free plan

The Free plan keeps up to three scores and lets you view the sheet music for each. You can open lyrics files, play along with your own audio files, connect your own GitHub repositories and add tracks from them, and make scales and arpeggios in any key.

It does not include note, bar or moving-line highlighting, anything that needs the internet, an equaliser, key changes or other tools. The free version can be rolled out to a whole school through Apple's volume purchasing.
