I have used a number of similar products as a school leader with responsibility for data/ assessment, but 4Matrix remains the best in my opinion. The range of tools available for interrogating assessment data following a data drop is unrivalled (and grows with every update), it is easy-to-use for most competent middle leaders (though a little bit of in-house training will be needed for some of course!), and it is super quick for data admins to upload and quality assure the data collected.
