About 1,400 people achieved the CII's mortgage advice qualification in the April sitting of the exam, bringing the total number who have passed to 7,214.
Of the 2,537 candidates sitting the exam in April, 1,454 were successful, giving a pass rate of 57.3 per cent.
Mortgage advisers must reach the minimum qualification standard by the Mortgage Code Compliance Board's deadline of December 31. Maq, which is held in conjunction with the Financial Planning Certificate, will satisfy this requirement.
The CII says it is taking an active role in helping advisers meet the deadline by expanding and enhancing its range of Maq learning and revision materials.
It says this will improve candidates' chances of first-time success and enable them to choose a date which fits with their revision schedule and work commitments.
Measures introduced by the CII include online learning, more revision courses and three additional exam sittings this year.
