Yes, English proficiency is required for most jobs in Ireland. Since English is the main language of communication, you need good speaking and writing skills to work effectively. Some employers, especially in healthcare or education, may ask for IELTS or TOEFL scores to check your language ability. Strong English skills also help during interviews, client meetings, and daily work communication. If English is not your first language, it’s a good idea to take short courses or practice regularly before applying for jobs.
