Take your existing network infrastructure skills to new levels allowing you to successfully control and deliver major infrastructure projects.

The Certified Network Infrastructure Technician (CNIT®) program is a comprehensive program perfect for those with at least 4 years of verifiable experience within the network infrastructure sector, or relevant qualifications, who wish to extend their knowledge, practical hands-on skills, qualifications and certifications into a wider project environment.

The five-day program aims to develop the knowledge and skills required to perform the multi-faceted role of a site delivery manager. Learners will greatly enhance their technical knowledge through a complex case study mastering the requirements for making survey decisions regarding spaces; pathways and containment, managing health and safety procedures and delivering a complex task schedule. They will also gain a valuable insight into the need to establish effective communications with key stakeholders. A certified CNIT® will be undaunted when dealing with escalations and problem resolution within a strategic network infrastructure project.

The CNIT® also takes into account the requirements of the current BS EN, TIA and ISO standards, whilst also meeting the architectural and technical requirements. During the program learners will also have access to current standards for reference purposes.

Current and emerging networking technologies will also be explored including Ethernet, Wireless and POE LANs. Principles of Intelligent Buildings also feature with insights into Building Management Systems (BMS) and Building Automation Systems (BAS).

Practical hands-on sessions are incorporated throughout this program, including a focus on advanced copper and fibre infrastructure troubleshooting, wireless survey and wireless network testing tools. The organisation and management of cable test results through OEM software with the latest features and capabilities exploited in detail.

On successful completion learners can demonstrate the highest levels of knowledge, competency and confidence in complex site environments, demonstrating efficiencies in both time and cost, coupled with the knowledge of the very latest technical capabilities dominating network infrastructure today.

A CNIT® can also feel confident that they are progressing through The Global Network Infrastructure Education Framework. They also gain an internationally recognised BTEC Level 4 Professional qualification and official CNIT® certification. This certification enters the learner into a commitment to life-long learning and offers the perfect portal to ensure knowledge; skills and certification remain current and up-to-date. Each certification gained from CNet Training requires re-certifying every three years. The process is simple, cost effective and easy via an online learning management system allowing knowledge to be brought up-to-date to reflect the very latest changes and technical developments within the industry. Re-certified learners can also benefit from utilising the latest program material, can continue to use the CNIT® logo and post nominal letters for the next three years.


This program is designed for those wishing to extend their knowledge, practical hands-on skills, qualifications and certifications into a wider project environment as a Site Delivery Manager with aspirations to progress into roles such as:

  • Site Supervisor (Team Leadership, Health & Safety Management)
  • Site Logistics Manager (Task Management, Stores & Equipment Co-ordination)
  • Technical Lead (Surveyor, Resolver, Quality Assurance, Project Closure)

Delegates will learn how to

  • Certified Network Infrastructure Technician (CNIT®) Certification
  • BTEC Level 4 Professional Award
  • Use of CNIT post nominal title e.g. Martin Smith CNIT
  • Use of the CNIT® logo
  • Eligibility for an ECS (Electrotechnical Certification Scheme) Datacomms Technician CNIT® card (only available in the UK)
  • Continual Professional Development (CPDs)
  • 5 IEEE Continual Education Units (CEUs)

Successful learners will have the knowledge, competency and confidence in complex site environments.
