Higher Technical Qualifications

Higher Technical Qualifications

Higher Technical Qualifications (HTQs) are an alternative to apprenticeships or degrees.

They have been specifically designed with employers to ensure learners get the skills that employers have said they need. They are a quicker and cheaper alternative to a degree and can lead to higher wages early in a career.

See all Computer Science HTQs

Example module
"Artificial Intelligence: This module explores the theory and practical implementation of artificial intelligence techniques, including machine learning, neural networks, natural language processing, and robotics."
Second year computer science student, Queen Mary University of London
Example project
"Creating an internet-of-things application using an arduino microcontroller and sensors seeing it used in the real world has been wonderful, and integrating mobile support was very cool. I just like making cool things and tinkering around."
Second year computer science student, Cardiff university

What is... a nanotechnologist?

Nope, we were stumped too. It’s someone who works with incredibly small things to develop new materials, equipment, drugs or tools. Nanotechnologists do their work with remarkable precision and control as they design experiments to work out uses for these tiny elements, from new technology to medical procedures. Studying computer science puts you at the forefront of innovation that is not only shaping the future of technology but also paving the way for solutions to some of society's most pressing issues. 

Getting in: Entry requirements

Find out more about what you'll need to study computer science at university or as an apprenticeship.

Average requirements for undergraduate degrees

Entry requirements differ between university and course, but this should give you a guide to what is usually expected from computer science applicants

A levels
Scottish Highers
Other Level 3/Level 6 qualifications (e.g. Pearson BTEC Level 3 National Extended Diploma in Computing, SVQ IT Professionals - SQCF Level 6) may be accepted as an alternative

The expert view

Institute of Analysts and Programmers
Specific entry requirements vary considerably, depending on the focus of the course. For example, a very theoretical course may require A level Mathematics, whereas Business IT programmes would probably not ask for any science background beyond GCSE. Few courses specify A level Computing or equivalent.

Considering an apprenticeship?

Applying for an apprenticeship is just like applying for a normal job. Here’s what you need to know:

  1. Deadline

    Apprenticeships don't follow the same deadlines as applying to uni, the deadline is down to the employer.
  2. Where to apply

    You apply directly through the employer.
  3. No limits

    You're not restricted to one apprenticeship application; you can do as many as you like.
  4. Apply to university and apprenticeships

    There's nothing stopping you applying to university through UCAS, while also applying for apprenticeship vacancies.
