Personnel standards.^*

Gold standard	•Diagnosis made by an evaluator fluent in the native language with advanced training and expertise in 0–5 assessment and with the highest level of training as defined by the specific setting (e.g., HIC or LMIC). •Diagnosis in a specific domain made by a specialist in that domain (e.g., a speech/language therapist). This specialist should have advanced training and expertise in 0–5 assessment and have the highest level of training as defined by the specific setting.
Below gold standard	•Diagnosis made by an evaluator with advanced training and the highest level of training as defined by the specific setting, but without or less expertise in 0–5 assessment. •Domain specific specialist as defined by the setting (e.g., a speech/language therapist) for each domain assessed without or less expertise in 0–5 assessment. •Nurse or equivalent health care provider, as defined by the highest level of training for the specific setting, with expertise in 0–5 assessment. •Domain specific specialist as defined by the setting with expertise in broad-based 0–5 assessment, or assessment of skills outside of the area of primary expertise (e.g., a speech/language therapist evaluates motor and cognitive functioning).
Well below gold standard	•Diagnosis made by a trained provider or community health worker with at least minimal training in 0–5 neurodevelopmental assessment.

^*For the purpose of research studies, personnel can move up one level from the level at which they are placed by their training and background (i.e., from well below gold standard to below gold standard or from below gold standard to gold standard) if they are administering a specific measure on which they have been adequately trained by gold standard personnel.
