There are reports that some parents who are desperate for extra teaching help for their children are paying for them to be formally diagnosed with disabilities.
Currently students need to fall into a certain category before support is provided by the Department of Education.
The practice known as "diagnosis for dollars" is common for conditions such as ADHD in the States.
Reports say the system is causing problems for poorer parents who cannot afford private consultations.
The Irish Indepepndent report that the head of the National Council for Special Education (NCSE), Teresa Griffin, has admitted that the practice is now happening here.
Psychologist David Carey is shocked by the accusations.
He said: "Now I don't know if it's happening or not, but I would be quite stunned to think that anyone would say 'Oh yes' and deliberately misdiagnose children with ADHD or some other condition so that they can get additional support in school."
