IntroductionExecutive Order (E.O.) 13526 and its implementing directive, 32 C.F.R Part 2001, prescribe a uniformsecurity classification system. This system requires that standard markings be applied to classifiedinformation. Except in extraordinary circumstances, or as approved by the Director of the InformationSecurity Oversight Office (ISOO), the marking of classified information shall not deviate from the prescribedformats. Markings shall be uniformly and conspicuously applied to leave no doubt about the classified statusof the information, the level of protection required, and the duration of classification. Since a booklet of thissize cannot illustrate every conceivable situation, please refer to the implementing directive, other ISOOissuances, and any instructions issued by your organization for further clarification. Consult your securitymanager if you have any questions.This booklet is unclassified, and as it is in the public domain, it may be reproduced without permission. Allclassification markings used are for illustration purposes only. All previous booklets and the guidancecontained in them are rescinded.Reminders Only individuals specifically authorized in writing may classify documents originally. Only individuals with the appropriate security clearance, who are required by their work to restateclassified source information, may derivatively classify information. The terms “Top Secret,” “Secret,” and “Confidential” are not to be used to mark executive branchinformation that has not been properly designated as classified national security information underE.O. 13526. Information shall not be classified for any reason unrelated to the protection of the national security. Classifiers and authorized holders are responsible for ensuring that information is appropriately classifiedand properly marked. Individuals who believe that information in their possession is inappropriately classified, or inappropriatelyunclassified, are expected to bring their concerns to the attention of responsible officials. The following markings are not authorized in the “Declassify On” line:• “Originating Agency’s Determination Required” or “OADR” for documents created afterOctober 14, 1995;• “X1,” “X2,” “X3,” “X4,” “X5,” “X6,” “X7,” or “X8” for documents created afterSeptember 22, 2003;• “Manual Review” or “MR;”• “DNI Only” or “DCI Only;” and• “Subject to treaty or international agreement.” The “25X1-human” marking may be used only when a derivative classifier is carrying it forward from asource document.- 2 -

Section 1: Originally Classified DocumentsThe following is an example of a document that an original classifier has determined requiresprotection under E.O. 13526. It contains the primary markings required under the Order, including: Portion markings; Overall classification markings; and Classification authority block consisting of:• A “Classified By” line to include the identity, by name and position, or by personalidentifier of the original classifier, and if not otherwise evident, the agency and office oforigin.• The “Reason” for classification as provided in section 1.4 of the Order.• A “Declassify On” line which shall indicate one of the following durations of classification: A date or event for declassification that corresponds to the lapse of theinformation’s national security sensitivity, which is equal to or less than 10 yearsfrom the date of the original decision. A date not to exceed 25 years from the date of the original decision. If the classified information should clearly and demonstrably be expected to revealthe identity of a confidential human source or a human intelligence source, no dateor event shall be annotated and the marking “50X1-HUM” shall be used. If the classified information should clearly and demonstrably be expected to revealkey design concepts of weapons of mass destruction, no date or event shall beannotated and the marking “50X2-WMD” shall be used.NOTE: Ensure the document you create is dated. Having the correctdate of origin of the document may be critical when creating otherdocuments using your originally classified document as a source.- 3 -

Step 1 – Portion marking Identify the classification level of each portion.• A portion is ordinarily defined as a paragraph, but also includes subjects, titles, graphics,tables, charts, bullet statements, sub-paragraphs, classified signature blocks, bullets andother portions within slide presentations, and the like.• Portion markings consist of the letters “(U)” for Unclassified, “(C)” for Confidential,“(S)” for Secret, and “(TS)” for Top Secret.• The two paragraphs of this sample document contain “Secret” and “Unclassified”information, respectively.• The abbreviations, in parentheses, are placed before the portion to which they apply.Portion mark as illustrated in this example.Department of Good WorksWashington, D.C. 20006June 27, 2010MEMORANDUM FOR THE DIRECTORFrom: John E. Doe, Chief Division 5Subject: (U) Examples1. (U) Paragraph 1 contains “Unclassified” information.Therefore, this portion will be marked with thedesignation “U” in parentheses preceding the portion.• (S) If all sub-paragraphs are the same classificationas the primary paragraph, then you do not need toportion mark the sub-paragraphs.• (U) However, if the portions are not all the sameclassification, then all main and sub-paragraphs mustbe individually marked.2. (S) Paragraph 2 contains “Secret” information.Therefore, this portion will be marked with thedesignation “S” in parentheses preceding the portion.NOTE: Portion marking waivers may be requested by an agency heador senior agency official. Such requests shall be submitted to theDirector of ISOO. See 32 C.F.R. Part 2001.24(k) for more information.- 5 -

Step 2 – Overall classification marking Identify the overall classification of the document. This will be equal to the highestclassification level of any one portion found in the document. In this example, the highestclassification is “Secret,” found in paragraph 2.• Conspicuously place the overall classification at the top and bottom of the page.• If the document contains more than one page, place the overall marking at the top andbottom of the outside of the front cover, on the title page, on the first page, and on theoutside of the back cover (if any).• Mark other internal pages either with the overall classification or with a markingindicating the highest classification level of information contained on that page.SECRETDepartment of Good WorksWashington, D.C. 20006June 27, 2010MEMORANDUM FOR THE DIRECTORFrom: John E.

Section 2: Derivatively Classified DocumentsDerivative classification is the act of incorporating, paraphrasing, restating, or generating in new forminformation that is already classified, and marking the newly developed material consistent with themarkings of the source information. The source information ordinarily consists of a classifieddocument or documents, or a classification guide issued by an original classification authority.When using a classified source document as the basis for derivative classification, the markings on thesource document determine the markings to be applied to the derivative document. When using aclassification guide as the basis for derivative classification, the instructions provided by the guide areto be applied to the derivative document.The following examples are of a properly marked source document and a properly marked derivativedocument, followed by the steps taken to create the derivative document.Source DocumentJune 27, 2010Department of Good WorksWashington, D.C. 20006MEMORANDUM FOR THE DIRECTORFrom: John E.

Classification by CompilationSection 1.7(e) of E.O. 13526 states that compilations of items of information that are individuallyunclassified may be classified if the compiled information reveals an additional association orrelationship that: (1) meets the standards for classification under this order; and(2) is not otherwise revealed in the individual items of information. The Order also definescompilation as an aggregation of pre-existing unclassified items of information.For the purpose of marking a document, this means that it may be possible to have a classifieddocument in which all the individual portions are unclassified but because the compilation of theunclassified information reveals an association or relationship not otherwise evident when theportions are used individually, classification of the document and the application of requiredclassification markings are warranted. In these cases, as required by 32 C.F.R. Part 2001.24(g),clear instructions must be provided as to the circumstances under which the individual portionsconstitute a classified compilation and when they do not.Two additional crucial points to consider are: (1) as with all other markings, information must bemarked in a uniform and conspicuous manner so as to leave no doubt as to the classified status ofthe information, the level of protection required, the reason for classification, and the duration ofclassification; and (2) access to or the sharing of unclassified information must not be impeded byunnecessarily or inappropriately applying classification where it’s not warranted.Examples of markings that may be applied to documents that are classified by compilation are onthe next page.- 30 -
