Ed-tech utilisation and spending are growing significantly in absolute terms and as a proportion of overall school budgets. This is happening alongside rising user expectations, increasing use of unauthorised “shadow IT”, and powerful education mega-trends that are driving increased reliance on technology. Navigating these changes is particularly challenging when selecting and deploying the core systems school staff rely on to keep each school running – their School Management Systems (SMS)1 and Learning Management Systems (LMS). These systems in particular require wholesale change across many areas of school activity, impacting users across the whole school community. Selecting and deploying the right core operating system is therefore one of the most challenging decisions facing school leadership teams today.
