What is Gartner Score?
Gartner Score is both a maturity assessment and prioritization tool. It measures your organization’s maturity across a comprehensive set of critical activities. The tool evaluates your current maturity level for each activity against objective, research-based performance standards. It also helps you identify priorities for improvement based on how important the activities are to your strategic objectives. 
Gartner IT Score is now Gartner Score
On 29 April 2019, the IT Score was redesigned and launched with a new methodology and report structure known as IT Score under the Gartner Score Diagnostic Family. This new IT Score replaced the legacy IT Score tool.
