Sustained attention for everything is about 1 minute, including remembering verbal directions and maintaining their attention on what they are doing. Recuing and repeating directions can be necessary about once a minute. The same action may be done several times within that minute.
With recuing, sessions can be scheduled for 30 to 45 minutes. On site supervision will be required the whole time.
Small groups of four to five people doing the same or similar activities can work beside each other. Most people seem to appreciate the company, and one experienced carer can recue several people who are functioning within the range of ACL 3.4 to 4.4.
