It isn't currently possible to delete a progress review.
If the review hasn't been started then you can can reschedule or cancel it and change or remove the employer contact in attendance.
Once a review has started, it must be completed. If you are no longer able to obtain signatures or if the review was started in error, Bud recommends signing offline and adding a note to the learner record to explain the error.
Once the review has been completed, it is not possible to make any further changes.
