To pass TLI certification requires you attain, with the assistance of our training, a baseline of skills necessary for successful technology leadership.
The training is not designed to be an exhaustive technical undertaking, technology leadership requires a balanced set of technical and non technical skills.
If you have limited experience in core technology areas (data, software, networking, security, web, etc.) then TLI will be difficult, but will help you to achieve a baseline knowledge in those areas.
