The PTIT believes that Human Resource Development must be carried out systematically across a wide spectrum of both professionally-qualified and non-qualified employees so that no single group develops too far ahead of any others. Only then, will organizations function as effectively as possible at corporate level while also encouraging excellence from individual employees.

Professionally-qualified employees can benefit from the Institute's training courses, technical workshops, seminars, conferences, and international symposia. Those without professional qualifications, including many members of the public, can receive more general information about Thailand's petroleum and petrochemicals industries through various public lectures and television presentations arranged by the PTIT, as well as from the Institute's petroleum industry storybook.
