IT Support Levels – An Overview

IT support levels are a way to categorize the types of issues that IT professionals can handle and the level of expertise that is involved. In other words, it is a hierarchical system where different levels of technical expertise are required to resolve the issues. 

The different IT support levels are as mentioned below: 

Level 0- It is a self-service option that does not involve human interaction. 

Level 1– It is basic support for common issues such as password reset or troubleshooting

Level 2- It is technical support for more complex issues related to software or hardware. 

Level 3- It is an expert support for advanced issues such as IT infrastructure management. 

Level 4- It refers to the third-party support that the organization is unable to solve themselves. 

Each IT support tier increases in technical expertise making room for efficient problem resolution depending on the issue’s complexity. 

Most organizations use levels and tiers interchangeably but there is a minute difference between the two. The levels refer to the broader range of expertise within the same team whereas tiers denote the complexity of issues handled by different levels of IT support.
