Administrators of the ACLS must consider all relevant factors when assigning a score to get reliable first estimate of abilities. A COTA with appropriate qualifications may administer the ACLS and assign scores. An OTR who works with a trained COTA should probably seek training in administration from the COTA. The OTR is responsible for interpreting the meaning of ACLS scores and scores from other related assessments to develop interventions that target identified goals in collaboration with the client and/or caregivers.
