It should be emphasised that not all children experiencing learning problems will necessarily go on to be diagnosed with a learning disorder. Some children mature more gradually and are slower in developing certain skills. However, given that any delay in development may put a child at risk of a wide range of problems, including social and emotional difficulties, it is important to have a full assessment of difficulties if learning problems are suspected.
While individuals experiencing learning problems can be identified by observing their behaviour and achievement, actual diagnosis of a specific learning disorder requires formal assessment conducted by a psychologist using standardised psychological and achievement tests. These tests compare the person’s level of ability to that which is considered normal development for someone of that age.
The first step in this process involves ruling out other possible causes of the difficulties being experienced, such as a sensory problem (e.g., visual or hearing impairment), emotional disturbance (e.g., depression), environmental factors (e.g., cultural or economic disadvantage or a lack of access to adequate education) and intellectual disability. All of these can also have an effect on learning.
Once these other possible causes of learning problems have been ruled out and it is determined that the individual has a specific learning disorder, then the second step should involve a more detailed diagnostic assessment, again using standardised tests administered by a psychologist with appropriate training in assessing learning disabilities in children, adolescents or adults.
In some instances psychologists may seek input from other professionals, such as speech pathologists. This second step provides more detailed information regarding the persons’s strengths and difficulties in language and literacy and forms the basis of a treatment plan.
