This file contains the Content Model Knowledge data associated with each O*NET-SOC occupation. It is displayed in 12 tab delimited fields and identified using the column names provided above. Item rating level metadata is provided in columns named n, standard_error, lower_ci_bound, upper_ci_bound, recommend_suppress, not_relevant, date_updated, and domain_source. Refer to Appendix 2, Item Rating Level Statistics - Incumbent for additional information on these items. The 12 fields are represented by one row. There are a total of 59,004 rows of data in this file.
