@nanurze Ang nakalagay na requirement sa AGOS-40 form ay Experience Certificate o Employment Certificate lang pero may mga instances na di naglalagay ng details like job description at no of hours ang employer kaya to supplement kumukuha ng recommendation letters from supervisors or Chief Nurse.
As a suggestion, since you will be needing that certificate after BP for ANMAC assessment and eventual visa processing, gayahin mo na ang ANMAC format. Will save you time and effort and money specially kung malayo sayo ang past work mo. At kung di naman kalabisan, make separate copies of the same addressed to AHPRA, ANMAC and Department of Home Affairs.
Also this early have your documents scanned and be sure to keep backup copies and backup copies of copies in a safe and secure place. AHPRA kasi requires paper submissions of certified true copies, ANMAC requires online submission of colored scans of originals at 600 dpi resolution or certified true copies if from photocopies or b/w documents. DHA requires colored scans of certified true copies of documents but not exceeding 5mb per document type.
