Skills development programs are used to help a person functioning within ACL 4 High to learn new skills. They are particularly important for someone who has never been functioning higher than ACL 4 High. The person is unable to pay attention to hints by caregivers to change their behavior.
Daily repetition of the new skill with frequent prompting is required to establish the new behavior. Once the new skill is rote learnt and is well established into the person's procedural memory, regular practice is still required otherwise this new skill will fade over time.
