O*NET databases from O*NET 98 to O*NET 4.0 were populated using data supplied by occupational analysts. To develop this data, analysts evaluated and refined existing occupational data, then extrapolated these data to the O*NET content model. Originally published as part of the O*NET 98 Data Dictionary, this document describes the process. New data is currently being collected that will gradually replace the existing analyst data. Questionnaires are being used to collect data for 4 O*NET Content Model domains, with analyst ratings being used to update a 5th domain.
