Special Educational Needs

This section is still under construction but we wanted to make sure information becomes available to you as soon as we have it.

Here are some initial points for you to consider if you are a parent or a teacher of a child with Special Educational Needs.

Colour vision deficiencies (CVD) are likely to affect the results of any tests to indicate other Special Educational Needs which include colours as part of the assessment. An example is the Rapid Colour Naming subtest of the CTOPP (Comprehensive Test of Phonological Processing) test which is used to indicate phonological processing and help identify dyslexia. Likewise the online Dyslexia Screener has a coloured shapes section which may also cause problems. Before using any such screening tests check them for potential colour issues and refer to the producers if you are unsure.

Be aware that even though a software package might have been produced by a specialist in Special Educational Needs this does not necessarily mean the software takes account of colour vision issues because at present CVD is not considered to be a SEN.

As mentioned in the Types of Colour Vision Deficiency section, children with some other visual impairments such as glaucoma and retinitis pigmentosa, are also more likely to have colour vision defects which may not present in the same way as genetic red/green colour blindness – i.e. different colours may be affected.

Without a Visual Impairment Statement it will be difficult or impossible to get access to Visual Impairment services for a child with CVD. Hence if you suspect a child is showing signs of possible CVD it is extremely important to arrange for a child to be tested and diagnosed with a Statement to ensure you can fully access support.

Children with colour vision problems who also have other special educational needs are far more vulnerable than CVD children in mainstream school environments not only because they may not be able to verbalise their inability to distinguish some colours but also because colour is an inherent part of educational tools for early years teaching and for teaching to special needs.

Therefore it is extremely important for teachers and carers to be able to identify whether a child with special needs might be colour blind, especially a non-verbal child so that they can specifically tailor teaching aids to the needs of the individual child.
