The reader groups of ETR include people with different linguistic difficulties. The following reasons increse the probability of needing Easy to read:

 

• Persons with permanent neuro biological brain dysfunctioning (e.g. persons with intellectual disability, persons with Asperger-syndrome etc.)
• Speakers with acquiered neurological dysfunctioning (e.g. persons with memory illness, aphatic persons etc.)
• Speakers with temporary linguistic deficiences (e.g. language learners, minority language speakers)

All readers are individuals with their strengths and deficiencies in reading. To belong in one group does not automatically mean a need for ETR.

 

It is worth of noting that when more than one of these reasons occur at the same time (e.g. developmentally disabled aged person), immigrant schoolchild with dysphasia), the need for Easy to read is even more pronounced.

In addition to the groups mentioned above, ETR can be useful for persons receiving rehabilitative treatment for mental problems, marginalized persons, those who are not accustomed to read, and school children.
