When compared to their peers without motor difficulties, students with developmental coordination disorder are seven times more likely than typically developing students to achieve very poor scores in visual-spatial memory. As a result of this working memory impairment, students with developmental coordination disorder have learning deficits as well. Psychological and social consequences
Psychological domain: Children with DCD may struggle with lower self-efficacy and lower self-perceived competence in peer and social relations. Some demonstrate greater aggressiveness and hyperactivity.Social domain: Children may be more vulnerable to social rejection and bullying, possibly resulting in higher levels of loneliness. Diagnosis
Assessments for developmental coordination disorder typically require a developmental history, detailing ages at which significant developmental milestones, such as crawling and walking, occurred. Motor skills screening includes activities designed to indicate developmental coordination disorder, including balancing, physical sequencing, touch sensitivity, and variations on walking activities.The American Psychiatric Association has four primary inclusive diagnostic criteria for determining if a child has developmental coordination disorder. The criteria are as follows:

Motor coordination will be greatly reduced, although the intelligence of the child is normal for the age. The difficulties the child experiences with motor coordination or planning interfere with the childs daily life. The difficulties with coordination are not due to any other medical condition
If the child does also experience comorbidities such as intellectual or other developmental disability; motor coordination is still disproportionally affected. Screening tests
Currently there is no single "gold standard" assessment test for DCD. Various screening tests may be used, including the following.
