The DPI qualification is available for Advanced Learner Loans which as of the 2016/17 academic year are expanded to learners from the age of 19 and to include designated qualifications up to level 6.
The loan applies to tuition fees for DPI preparation courses delivered by colleges or training providers in England approved to offer loans by the Skills Funding Agency. Please check with the course provider to find out about their eligibility and availability of a course.
Loans are available for learners starting a course after 1 August 2017. The last date for enrolment in any future course will be 31 July 2018.
Please note that IoLET does not offer courses and therefore does not deal with any aspects of these loans. As the Awarding Organisation our role is limited to nominating the qualification for Advanced Learner Loans designation.
The examination is open to anyone who wishes to take it. There are no absolute entry requirements, but regular attendance on a course is strongly recommended.
