The GATE score is valid for three years from the date of announcement of the results. During this period, candidates can use their score to apply for admission to postgraduate programs such as M.Tech, ME, MS, and PhD in various institutions across India. Many Public Sector Undertakings (PSUs) also consider GATE scores for recruitment within this validity period. However, some institutions or organizations may have their own specific rules regarding how recent the GATE score must be for admission or recruitment purposes.
