The proportion of educators in upper secondary schools who have undergone formal training reflects the quality and preparedness of the teaching workforce in a country's education system. This metric highlights the percentage of teachers who have attained the essential qualifications, whether through pre-service training programs or ongoing professional development, ensuring they are equipped with pedagogical skills and subject knowledge. A high
percentage of trained teachers often correlates with improved student outcomes, as these educators are better prepared to engage with diverse learning needs and employ effective teaching strategies. Additionally, this indicator provides insight into the investment a country makes in educational quality, which can have far-reaching implications for economic development and social mobility.
