The SOLAS Electrical Apprenticeship is Ireland's craft pathway to qualifying as an electrician, placed at NFQ Level 6 and awarded as a QQI Advanced Certificate Craft. Apprentices complete seven alternating on-the-job and off-the-job phases and sit modular written theory papers (multiple-choice and short-answer) plus practical assessments. The theory covers electrical science and circuits, wiring systems and installation, the I.S. 10101:2020 National Rules for Electrical Installations (the successor to ET101), inspection and testing, machines and motors, electronics, controls, and safety and safe isolation. Ireland uses a 230 V single-phase and 400 V three-phase 50 Hz supply, harmonised brown/blue/green-yellow cable colours, and 30 mA RCD protection for socket-outlets. This free prep includes 100 research-based practice questions with explanations and an AI tutor.

About the SOLAS Electrical Apprenticeship Exam
The SOLAS Electrical Apprenticeship is Ireland's recognised craft route to becoming a qualified electrician, leading to a QQI Level 6 Advanced Certificate Craft on the National Framework of Qualifications. Apprentices alternate on-the-job and off-the-job phases and sit modular written theory papers covering electrical theory, wiring systems, the I.S. 10101 national wiring rules, inspection and testing, machines, electronics, controls, and safe isolation.
Exam sponsor: SOLAS (Further Education and Training Authority), with QQI awarding the Level 6 certificate. The requirements and fees below concern the certification or admission exam, separate from our free practice resources.
Assessment
Modular written theory papers (multiple-choice and short-answer) sat at each off-the-job phase, alongside practical skills assessments; awarded as a QQI Level 6 Advanced Certificate Craft on completion. This practice bank is 100 selected-response items.
Time Limit
Varies by phase module (commonly 1-2 hours per written paper)
Passing Score
Typically 40% to pass each module assessment (thresholds vary by provider; confirm locally)
Exam / Certification Fees
No separate exam fee; apprenticeship registration fee applies and off-the-job phases are largely state-funded
Exam sponsor websiteFees, eligibility, and exam policies can change. Confirm them with the exam sponsor before applying or paying.

SOLAS Electrical Apprenticeship: Suggested Study Strategy
Frequently Asked Questions
What qualification does the SOLAS Electrical Apprenticeship lead to?
It leads to a QQI Level 6 Advanced Certificate Craft (Electrical) on the National Framework of Qualifications, the recognised trade qualification for electricians in Ireland. Apprentices complete seven alternating on-the-job and off-the-job phases over about four years.
Which wiring rules does the SOLAS electrical exam test?
It tests I.S. 10101:2020, the National Rules for Electrical Installations published by the NSAI, which replaced ET101:2008. This is the Irish standard, not the UK's BS 7671 or the US NEC, so values such as RCD requirements and disconnection times follow I.S. 10101.
How are the SOLAS electrical phase exams structured?
Each off-the-job phase includes modular written theory papers combining multiple-choice and short-answer questions, plus practical skills assessments. SOLAS does not publish a single fixed exam length; the number of questions and time vary by phase and module.
What score do I need to pass?
Module assessments are typically passed at around 40%, with higher thresholds for merit or distinction, but exact marks vary by provider and phase. Confirm the pass requirements with your education and training board or technological university.
What is the standard Irish supply the exam refers to?
Ireland uses a 230 V single-phase and 400 V three-phase supply at 50 Hz, distributed by ESB Networks. Harmonised cable colours are brown for line, blue for neutral, and green-and-yellow for the protective conductor.
Is this free SOLAS electrical practice as good as paid prep?
Our 100 practice questions cover all the apprenticeship theory domains, including I.S. 10101, with a teaching explanation for every answer plus free daily AI tutor interactions. All content is free forever and updated for 2026.
