4Matrix is an amazing piece of software that has saved hours of time that would usually be spent on data analysis. I used it for the first time in July of this year and I was extremely impressed with what it will do. Whether you wish to examine your data at individual student, teacher or subject level; it lets you do it with a few clicks of your mouse. It is intuitive to use and the support that you receive from the team is first class. I would recommend it to any school that wants to further empower their middle leaders to reduce In-School Variation as it removes the burden of time spent doing calculations and counting, and frees them to spend the time getting under the skin of departmental performance and changing things for the future. In my opinion, it is also incredibly good value.
