Research Integrity

Notice On Research On Children With Special Educational Needs

4 April 2016 


As a top-ranked global university, Nanyang Technological University (NTU) upholds the highest research standards and international best practices in research. NTU has zero tolerance towards any form of research malpractice and will not hesitate to take action against anyone found to be lacking in research integrity.

In accordance with its policy of research integrity, NTU conducted an in-depth investigation following allegations of research malpractice.

This concerned research in the area of children with special educational needs carried out by researchers at the NTU National Institute of Education.

Because of the non-availability of primary data we are unable to authenticate the data. Consequently, the University considers that coupled with doubts about the ethical approvals for the collection of the data, and in order to protect the integrity of its research record, the papers based on those data need to be retracted. Associate Professor Noel Chia and his co-authors have requested for the following papers to be retracted.

The authors and the papers are listed below:
