During its 23 years of service to teacher education as well as school education, DIET has the unique distinction of enabling 50 part-time vocational teachers, who had been working on a consolidated pay, to get regular appointment in Government schools with the scale of pay on par with that of the elementary teachers through its two-month training conducted on Child Psychology and Pedagogy in 1997. During the same year, 60 unemployed, B. T. qualified teachers belonging to the Scheduled Caste and Scheduled Tribe communities were provided with training on Child Psychology and Methodology to help them get regular posts as B.T. Assistants in Government Middle Schools throughout Tamil Nadu. In 1999, drop-out students, who had studied up to eighth standard, were given special training to help them appear for Class X board examination directly and 500 students benefited from this training provided by the DIET.

As directed by the Government of Tamil Nadu, two-year regular course was conducted for 862 teachers, whose diploma from unrecognized institutions got disqualified, so as to redress their woes of unemployment. These three batches appeared for the examinations in the years 2002, 2004 and 2007 and came out with flying colors securing pass percentage of 90, 88 and 99 respectively. In 2014, special coaching to face Teacher Eligibility Test was offered to Visually Challenged B.
