Draft OASIS data Specifications v2.11.0
A new version of the data submission specifications (v2.11.0) has been developed to support OASIS-C1. This new version is available for download below. Please refer to the overview document, the item change report, and the edit change report that are included in the ZIP file for details regarding the new version.
Note that both v2.11.0 (which supports OASIS-C1) and v2.10.0 (which supports OASIS-C) will be effective beginning on October 1, 2014. Please note that both versions of these specifications should be considered provisional or draft and are subject to change until the final specifications are published.
On February 24, 2014, an updated errata document was posted which addresses issues with both v2.10.0 and v2.11.0 of the data submission specifications.
Draft OASIS data Specifications v2.10.0
Beginning on October 1, 2014, the submission format for OASIS assessment data will change from the current fixed-format record layout to Extensible Markup Language (XML). When the new system is implemented, data will be submitted to a centralized system called the Assessment Submission and Processing (ASAP) system. ZIP files that contain one or more XML files will be submitted to ASAP. Each XML file will contain data for only one assessment record, and each data element within the XML file will correspond to an active item on the assessment.
A new version of the data submission specifications (v2.10.0) has been developed to support the new submission system. This new version is available for download below. Previous users of the OASIS data submission specifications should note that the structure of the data specification reports and of the data submission files themselves have changed substantially. All users of the specifications are strongly urged to carefully read the overview document that is included in the download file.
Please note that version 2.10.0 of these specifications should be considered provisional or draft and is subject to change until the final specifications are published.
Final OASIS-C Data Specifications Version 2.00
A final version of the OASIS-C Data Specifications Version 2.00 is now available. This version is a revision to the initial draft published in July, 2009.
