Credential
Elite Diploma in Enterprise Network Engineering

A 22-month elite diploma that begins where certification-first networking programmes spend their first months. NET 200 assumes the Tier 1 networking floor and teaches the engineering craft on top of it — campus switching, enterprise routing, infrastructure services, wireless, WAN, security hardening, assurance, and automation — until a graduate can walk into an enterprise network, understand what they are seeing, improve it safely, prove the fix, document the work, and defend the design.

What you'll become

  • Network Engineer
  • Network Operations Centre Engineer
  • Infrastructure Support Engineer
  • Enterprise Network Technician
  • Wireless Network Technician
  • Network Automation Assistant
  • Network Security Support Engineer
  • ISP / Enterprise Support Engineer
  • Branch Infrastructure Engineer
  • Junior Network Consultant

§ 01 · The difference

What sets this programme apart.

01

Foundation Is Assumed, Not Repeated

FND 55 already teaches the networking substrate — layered models, IP, subnetting, routing concepts, DNS, DHCP, TLS, Wireshark, and small-network design. NET 200 starts above that line. A student who cannot clear the floor is routed back to the foundation gate before entering the diploma.

02

Configuration Is Evidence

A diagram is not proof. A spoken explanation is not proof. A vendor slide is not proof. The network must run. Every module produces working configurations, validation evidence, diagrams, change notes, and a defensible Git history.

03

Troubleshooting Is a Discipline

Students do not guess. They isolate failure by layer, compare expected state against observed state, use commands and captures as evidence, and document root cause. Troubleshooting is not a week at the end — it is the method used throughout.

04

Vendor Skill Without Vendor Lock-In

Cisco is the primary training environment because it remains the dominant enterprise-networking language in the market. But the diploma teaches transferable judgement — addressing, routing, segmentation, high availability, observability, security, documentation, and change control.

05

Automation Belongs in Network Engineering

Modern network engineers cannot remain purely manual CLI operators. NET 200 uses Python, structured data, APIs, Git, and configuration-management concepts to automate repeatable work and reduce operational risk.

06

West African Network Reality Matters

Students work with realistic constraints — branch connectivity, ISP instability, latency to international destinations, limited budgets, mixed equipment, mobile-money dependencies, school networks, microfinance branches, and uptime expectations under imperfect infrastructure.

§ 02 · Who this is for

Built for engineers ready to operate at depth.

The Aspiring Network Engineer

You want to build and operate the networks that keep organisations alive — switches, routers, wireless, branch connectivity, monitoring, security controls, and incident response when the network fails.

The IT Technician Moving Up

You already support users and devices. You want to move from 'restart the router' to understanding the topology, the route table, the VLAN design, the logs, and the policy.

The Infrastructure-Minded Technologist

You are interested in cloud, security, telecoms, or systems — but you know the network is the substrate, and you want professional network fluency before specialising further.

The Future Infrastructure Lead

You want to design reliable infrastructure for banks, schools, hospitals, NGOs, government departments, and growing technology companies in the region.

§ 03 · The Tier 1 floor

What you need before you start.

This is an advanced programme that begins above the foundation floor. Clear it by passing the WIATech technical assessment — or by completing the matching Tier 1 Foundations courses. The assessment is a placement instrument, never a rejection.

Required foundations

FND 55Networking Foundations

The required substrate — layers, IP, subnetting, routing concepts, DNS, DHCP, TLS, Wireshark, diagnostics, and small-network design. NET 200 does not re-teach these from zero; it builds enterprise engineering on top of them.

FND 45Linux & Command Line Foundations

Network engineers live in terminals — SSH, logs, packet tools, config files, scripts, and Linux-based appliances. NET 200 assumes command-line fluency.

FND 25Version Control with Git

Configurations, diagrams, automation scripts, validation checklists, and capstone artefacts must carry clean history. NET 200 operates a Git-backed configuration repository from Week 01.

FND 60Foundations of Programming with Python

Network automation, API work, JSON parsing, inventory checks, and validation scripts build on Python fluency. NET 200 automates network tasks; it does not teach Python.

Recommended · not required

FND 30Computer Systems Fundamentals

Strongly recommended for students who lack systems literacy. Not a hard gate, but it makes the early device-operations and services work considerably easier.

Universal parallel co-requisite

ENG 70English & Communication

Taken in parallel throughout the diploma by every WIATech student. Network engineers write change notes, outage reports, handover documents, design justifications, and executive summaries.

NET 200 is a Tier 2 Elite Diploma that begins above the foundation floor. Every student arriving in Semester 01 must have cleared the required Tier 1 foundations — FND 55, FND 45, FND 25, and FND 60 — by passing the technical assessment or completing the specific Tier 1 courses their results indicate. The portal is placement, not rejection. NET 200 does not require FND 40, FND 35, DAT 45, MTH 85, or WEB 35.

Direct entry

Applicants who can demonstrate the required foundations sit the NET 200 technical assessment and interview directly. A pass certifies that the foundation floor is already crossed and routes the candidate straight into Semester 01.

Routed entry

Applicants who do not pass all required sub-scores are not rejected; they are routed to the exact Tier 1 courses they need. A candidate strong in networking but weak in Python may be routed to FND 60 only; one weak in subnetting and diagnostics is routed to FND 55.

§ 08 · Admissions

Who we admit. How we admit them.

Admission is selective with capped cohorts, and does not depend on credentials — no specific WASSCE results, university degree, or networking certifications are required. What is required is demonstrated capability, cleared either by passing the WIATech technical assessment or by completing the gated Tier 1 foundation courses. Prior IT, networking, or systems experience, a self-directed portfolio, or completed Tier 1 certificates all help, but none are required. Admission is on demonstrated capability, not credentials alone.

01

Application

Online application form, academic records, and a short statement of intent.

02

Technical Assessment

A WIATech-administered assessment covering the required Tier 1 floor — networking (FND 55), Linux (FND 45), Git (FND 25), and Python (FND 60) — plus diagnostic reasoning and written communication. Results route the candidate to direct entry or a specific Tier 1 path.

03

Technical Interview

The final word

Two years. One network engineer the enterprise can trust.

Every bank, hospital, school, microfinance branch, and growing company in Sierra Leone and West Africa runs on a network that has to work when the power is unstable and bandwidth is expensive. The engineers who design those networks, defend them, find the fault, and keep them running are not cable pullers and not certificate collectors — they are built. NET 200 builds them. It begins in November 2026. If that is you, apply.
