The scope of the Accuracy Checking for Dispensing Assistants (ACDA) course is to train dispensing assistants to carry out the final check of listed dispensed items clinically approved by a pharmacist. It does not encompass aseptic dispensing, self-checking of own dispensing or pre-packing. The ACDA course is dependent upon Standard Operating Procedures (SOPs) being in place for accuracy checking, which define the scope of what both a learner and fully qualified ACDA can and cannot check against a clinically screened prescription. The clinical and legal checks on the prescriptions must be completed by a pharmacist. On completion of the course, learners will be issued with a certificate which states that they are able to complete a final accuracy check under the supervision of a Responsible Pharmacist within a specified setting. Revalidation of the certificate is required every two years.
