About PhD Computer Science.
PhD Computer Science is presented in an Irish context using QQI qualification levels, provider-specific admission rules, CSO Q1 2026 earnings and employment evidence, and SOLAS skills-demand signals. The closest broad labour-market benchmark is Information and communication.
PhD Computer Science is localised for Ireland. The closest CSO sector benchmark is Information and communication, with average weekly earnings of €1,825, 2,300 vacancies and a 2.1% vacancy rate in Q1 2026. Sector employment changed -9.6% between Q1 2025 and Q1 2026. These are sector-level indicators, not a guaranteed occupation salary or job outcome.
Why PhD Computer Science can be a strong path.
📈
Irish market signal
SOLAS reports ICT as the fastest-growing occupational group over 2019–2024 and identifies shortages in software development, engineering and IT analysis. Current CSO sector evidence is shown separately from longer-term skills demand.
🧰
Evidence-first path
Projects, placements, labs, portfolios and documented outcomes remain the strongest proof of applied ability.
🎓
Irish qualification context
This route is mapped to NFQ Level 10 where applicable; final award level and accreditation must be checked with the provider.
🧭
Provider-specific route
CAO, direct application, regulated-profession and apprenticeship routes differ. Verify the actual programme before applying.
PhD Computer Science is presented for Ireland using the National Framework of Qualifications, provider-specific requirements and Irish labour-market evidence. The closest broad benchmark is Information and communication. Average weekly earnings were €1,825 and the sector recorded 2,300 vacancies in Q1 2026. These are sector-level indicators, not a guaranteed graduate salary or placement outcome.
