Errata for CDISC standards are collected and published here.


titleWhat are "errata"?

An erratum (plural: errata) is a correction of a published text. The term originated in the pre-digital age, and signified a mistake, by either the author or the printer, that was identified in the time between printing and distribution. If the mistake was significant enough that it could not be deferred to a later printing, yet not so significant that it required a complete revision, then an additional page for errata would be printed and tipped into each book before it left the printing house.

See also: Erratum on Wikipedia.

For CDISC standards, an erratum is a correction to a mistake made in a published standard, that which was identified after it was published on the CDISC website, and which would have been corrected in the current version had it been identified prior to publication. Updates, revisions, substantive¹ corrections, and other changes of enough significance to require a cycle through the standards development process are not errata, and thus are not included on the pages below.

¹ See the W3C Process Document Section 6.2.5 ( for definitions of editorial vs. substantive changes.


The errata on the following pages are described using a combination of:

  • Where the correction should be made in the published document, both by page number and by section number, and going into as much detail as necessary to clearly pinpoint the exact location of the change to be made.
  • A precise description of what change should be made to the document to correct the error.
titleFor example...

For example, a simple entry in the errata might look like this:

  • Page X / Section Y.Z, Nth paragraph: The final sentence of this paragraph should be deleted.  

Multiple corrections grouped by a common factor might look like either of the following:

  • Page X / Section Y.Z, Example N:
    • First paragraph, second sentence: The third word in this sentence, "whut", should be "what". 
    • qq.xpt: QQVAR in row 2 should be changed from "THIGNS" to "THINGS".

  • Page X / Appendix V: The kind-of-things should be renamed as follows: 
    • "WHUT" to "WHAT"
    • "THIGNS" to "THINGS"
    • "BLUSH" to "ROSE"

A large-scale correction may be best described by giving the equivalent of a sticker to paste over the original page or part of the page, like so:

  • Page X / Section Y.Z: Example N is updated as follows:

The existence of an Errata Page for a given standard does not necessarily mean that any errors have been identified. Similarly, the lack of an Errata Page for a standard does not necessarily mean that no errors exist in the document – or even that no errors have been identified.

Errors on a CDISC standard may be reported to the standards development team responsible for that standard in JIRA or via the contact form on the CDISC website.
