Currently, teachers have to go into each assessment and grade everything on that assessment before they can save and open the next student's assessment. If a teacher has mostly objective and automatically graded questions and the last one is an essay, it would be very helpful if they could just click to open the essay and grade all students' essays one after another then click save. Super time saver! And more teachers would be willing to use this feature.
It might be worth noting that one of your biggest competitors in the market is "Canvas" which is an interactive teacher learning platform and assessment software similar to Blackbaud but apparently with much wider ranging options to both share smaller groups collaborating together and sharing work AND a platform that also allows teachers to mark all of one question type in an assessment before moving on to the next question. It's the little things that can sometimes make the biggest difference!
