Data Analyst

As a Data Analyst you collect, clean, and interpret large datasets to help organisations make informed business decisions. Your daily work involves importing raw data from various sources, checking it for errors or inconsistencies, and applying statistical or algorithmic techniques to uncover patterns and trends. You present your findings through visualisations such as dashboards, charts, and reports that non-technical colleagues and management can easily understand. You typically collaborate with business analysts, software developers, and department managers to ensure data supports strategic goals. Maintaining data quality and confidentiality is a core responsibility in every industry you work in.

A Level 8 Honours Bachelor degree is the most common entry route, with relevant programmes including BSc Data Science, BSc Business Analytics, BSc Computer Science, and BSc Statistics offered at universities such as UCD, TU Dublin, University of Galway, and UL. Helpful Leaving Certificate subjects include Mathematics (Higher Level is strongly recommended), Applied Mathematics, Business, and Computer Science. Some graduates enter through a Level 7 Ordinary Bachelor in Computing or Business Information Systems and progress to a Level 9 postgraduate qualification such as an MSc in Data Analytics or MSc in Business Intelligence, available at institutions including DCU, UCC, and ATU. A QQI Level 5 or 6 PLC course in Computing or IT can serve as an alternative entry point into a Level 7 or Level 8 programme via the linked progression route. There is no statutory professional registration body for data analysts in Ireland, though professional certifications from bodies such as the Royal Statistical Society or vendor certifications (e.g. Microsoft, Google) are valued by employers.
