The user friendly UI makes it easy to use even if you have no prior experience of using assessment tools like this one! I love how simple yet effective their approach has been in helping us measure our learners' progress over time. It's not perfect; but they are constantly improving so we can see where things need workinng to improve results from previous versions. They also provide excellent customer support which helps when there seems to be some issue that needs immediate attention. We're currently testing them out as part of our new initiative towards continuous improvement within our organisation. There isn't anything at present that would make me say "no" about recommending them though. Their ability to help identify areas requiring further development or enhancement was very helpful.
