§ Tier 1 · Foundations

The foundation that prepares you — or stands on its own.

WIATech Foundations is a catalogue of short, focused courses — each with its own certificate. They clear the floor into an Elite Diploma, and they carry real, standalone value for the engineer who takes one and stops there.

A gate, not a wall

Sit the WIATech technical assessment. Clear every gate your target diploma needs and you enter directly. Miss one and you're routed to exactly the foundation that closes it — never rejected.

Self-decoding codes

A code tells you what it is. The prefix names the subject; for Tier 1, the number encodes the length in weeks. FND 60 is a ten-week Foundations course; FND 25, three weeks.

Credentials that count

Each course ends in its own assessment and a WIATech certificate in that subject — evidence you can show an employer whether or not you go on to a diploma.

The catalogue

Eleven foundations across the subjects WIATech teaches. You take only the ones your target diploma and your assessment route you to.

Computer Systems Fundamentals

A four-week intensive that builds the mental model underneath the code — bits, the CPU, memory and the operating system — so failures three layers above the metal become reasoning, not mystery.

Data Structures & Algorithms

A five-week intensive that builds algorithmic literacy — the structures, their costs, and the judgement calls that make engineering decisions automatic.

Foundations of Databases with SQL

Fluent SQL and competent relational modelling — the data floor every WIATech diploma assumes.
