From an email last week:

We’re excited to share a powerful update in Sight Reading Factory!

Rhythm-only auto assessment is now available — both for individual practice and for teacher-created assignments!

That means:

✅ Students and independent learners can now be automatically assessed on rhythm-only exercises
✅ Auto-graded rhythm-only assignments are fully supported for educators
✅ Rhythm is often the hardest part of sight reading – now you can isolate and assess it with ease.
In addition to rhythm-only auto assessment, make sure to check out the already released auto assessment feature

I know a lot of teachers have wanted this for a long time. I am glad to see the feature finally added.
