The Solomon Islands National Teachers Association (SINTA) has called on responsible authorities to seriously investigate circumstances surrounding the illegal sale of exam papers to students.

This follows recent allegations that certain printing firms have been involved in the selling of form five exam papers to parents and students prior to the form five exams two weeks ago.

Speaking during SIBC's Democracy and Accountability Program on Monday, SINTA's General Secretary Johnly Hatimoana says there is corruption in the national examination system especially with exam setters and Invigilators.

Mr Hatimoana says the Education Ministry is well aware of the matter and calls on Ministry and police to seriously investigate the matter and bring those responsible to justice.
