Having a positive and strong culture within a long-established history of 150 years, also maintaining its prestige in the eyes of public opinion and the other units of ministry, our institution gets into the act on the sixth floor of main service building of Ministry of Education in Ankara. 1 executive,6 department head, 500 inspectors, 50 staff member (expert, director, official) have been working in the central unit of our institution. Functionally connected to our headship, working within provincial directorates, all of our inspectors have been giving professional guidance and assistance service to the teachers working in our educational institutes all over our country. Consequently, our institution’s assigned position and influence is quite broad in a way to comprise the entire educational institutes and their staff. Guidance, professional assistance /development activities intended for directors, teachers and the other staff working in vocational and technical education institutes are carried out by education inspectors in the cordination of our headship. In order to raise the quality of those activities, guidance and professional assistance manuals have been prepared and great attention has been payed in order to perform the activities in accordance with the principles mentioned in the manuals.However, according to the acquired feedback and research made in that field, it has been understood that enough effiency can’t be obtained from the guidance activities done by classical methods without allowing enough time. Starting from these results, ıt has been agreed that, the methods and instruments used in guidance and professional assistance intended for the teachers working in vocational education institutes, should be modernised and the qualifiedness of the inspectors in this field should be developed, so some modifications have been put through. Our studies intended for building a more effecient guidance and professional assistance model which will aid the career development of the entire education staff members and specifically the teachers who work in vocational education institutes, are still in progress.
