Last January, MLA announced the Data Services Specialization (DSS) certificate that librarians can earn to demonstrate their attainment of the relevant knowledge and skills necessary to provide data services.
Best geared for health sciences librarians and information professionals and built upon the MLA Data Services Competency, the Basic Certification requires the completion of four 4-credit free Network of the National Library of Medicine courses. These courses cover 5 skill areas (i.e. principles of data literacy; data services; research data best practices across the data lifecycle, open science practices, and training and consultation on data-related topics) and are available on demand. An additional three credits in the five skill areas are required and several NNLM courses are listed on the NNLM Data Services Specialization page.
Registration for the NNLM courses is open and free. MLA DSS certification costs for MLA members is $55 and for MLA nonmembers is $75. You can find more information about the DSS certificate, including cost, requirements, and skills on the MLA website.
