An abbreviation is a shortened or contracted form of a word or phrase used to represent the whole.

• Examples: SPA, CCD, NCAA

An acronym is an abbreviation that is read as a word.

• Examples: SMART Registration System, CAM, NASA

General Rules

Use abbreviations and acronyms in moderation.

When using uncommon abbreviations or acronyms (ones that people outside of your field of study, school or department will not recognize) define them on first use—spell out the abbreviation or acronym followed by the abbreviation or acronym in parenthesis.

• Example: The College of Arts and Media (CAM) is sponsoring an art exhibit at the museum next month. Exhibits hosted by CAM are free to all students.

NOTE: If the abbreviation or acronym is not used after the first mention, do not abbreviate it.
Common-knowledge abbreviations and acronyms do not need to be defined on first use.

• Examples: GPA, GMAT, ACT, SAT

Use of Articles (a, an, the) with Acronyms and Abbreviations

Use the article that you would use when speaking.

• Examples: an M.A. degree, a Ph.D. degree

In general, if the acronym or abbreviation is used as a noun, no article is necessary.

• Example: The theater production is sponsored by CAM and CLAS (not the CAM and the CLAS).

Degrees

Include periods when abbreviating academic degrees fewer than three letters: B.A., BFA, M.A., Ph.D., M.D., etc.

Abbreviated Courtesy Titles

Use a period with abbreviated courtesy titles (Dr., Ms., Mr., Sen., Gov., etc.).

When possible, use degrees instead of courtesy titles; degree names are more accurate. Do not use both.

• Example: John Smith, DDS vs. Dr. John Smith (Dr. is a relatively general title);
  not Dr. John Smith, DDS

State Abbreviations

Use Associated Press (AP) state abbreviations. Never use the two-letter postal abbreviations, unless part of a complete mailing addresses.

• Examples: The Office of the President is located in Denver. The building address is 1800 Grant St., Denver, CO 80203.

Only abbreviate state names when used with the name of a city.

The list of AP state abbreviations is as follows:

United States / United States of America

Only abbreviate United States when it is used as an adjective.

• Examples: U.S. history; history of the United States

Use periods when abbreviating United States (U.S.).
Do not use periods when abbreviating United States of America (USA).

Do not capitalize the names of degrees.

• Examples: He earned a bachelor of arts degree in English. She will graduate with a master of science in nursing. He received a doctor of philosophy degree in history.

Use bachelor of, master of, and doctor of when using the name of a degree as a noun (see examples above). Use bachelor's degree, master's degree or doctorate when the degree name isn't specified or when the level of degree is used as an adjective.

• Examples: His bachelor's degree helped him get the job. Her master's thesis took nine months to write. A doctorate is required in order to teach. Incorrect: She's working on a master's of architecture.

The University of Colorado does not award associate degrees; however, employees may still need to reference this level of education. NOTE: Associate degree is never plural (associates) or possessive (associate's).
Abbreviating degree names is encouraged; use periods if fewer than three letters are abbreviated: B.A., BFA, M.A., Ph.D., M.D., etc.

• Example: He earned a Ph.D. in immunology.

Areas of study (e.g. music, genetics, physical therapy, electrical engineering) are not capitalized unless used as part of a proper name.

• Examples: He's studying toxicology on the University of Colorado Boulder. She has an internship in the theater department.

Addresses

Use abbreviations for Ave., Blvd. and St. with numbered addresses. Spell out and capitalize them when referencing a formal street name without a number.

• Examples: She lives at 123 Main St. The building is on Grant Street between 18th and 19th avenues.

When referencing two street names without a numbered address, spell out the type of street but do not capitalize it.

• Example: 14th and Lawrence streets

Abbreviate compass points when used with a number address. Spell out compass points in other uses.

• Examples: He works at 4321 E. Main St. He drove down East Main Street.

Always use figures for an address number.

Telephone Numbers

Use dashes, not periods. Do not put parenthesis around the area code.

• Examples: 303-315-3716, 202-456-1111

The “1” is not necessary when writing long-distance or toll-free telephone numbers.

When writing articles for publication or content for the web, be aware of federal privacy laws concerning patient and individuals’ health records and students’ academic records. The FERPA and HIPAA laws make it illegal to disclose personal information without the individual’s consent.

FERPA

The Family Educational Rights and Privacy Act [3] (FERPA) is a federal law that protects the privacy of student education records. The law applies to all schools that receive funds under an applicable program of the U.S. Department of Education. FERPA gives parents certain rights with respect to their children's education records. These rights transfer to the student when he or she reaches the age of 18 or attends a school beyond the high school level.

Students to whom the rights have transferred are "eligible students." ~ U.S. Department of Education

HIPPA

The Health Insurance Portability and Accountability Act of 1996 [4] (HIPAA) provides federal protections for personal health information and gives patients an array of rights with respect to that information. At the same time, the permits the disclosure of personal health information needed for patient care and other important purposes. The rule specifies a series of administrative, physical and technical safeguards for covered entities to use to assure the confidentiality, integrity and availability of electronic protected health information. ;~ U.S. Department of Health and Human Services

The Colorado legislative body is called the General Assembly, not the Colorado Legislature. If you refer to it as the Colorado legislature, it’s in lower case.
Most other states go by legislature as part of the proper name. It should therefore be capitalized when presented as the formal name. Example: The Kansas Legislature; the legislature in Kansas.

Legislative titles

First reference, use Rep., Reps., Sen. and Sens. as formal titles for one or more names. Do not capitalize the title when it follows a person’s name or stands alone.

• Sen. Darth Vader, R-New Hampshire, confronted Rep. Luke Skywalker, D-Michigan, in a heated debate.
• Darth Vader, the senator from New Hampshire, was last seen driving a white Ford Bronco.

Examples (acceptable):

• The vice president for budget and finance will issue new funding figures this month.
• Interior Secretary Ken Salazar will speak to CU Law School students.

Hyphenate compound modifiers—two or more words that modify the same noun.

• Examples: world-class university, full-time student

Hyphenate phrases to avoid ambiguity.

• Examples: small-business owner, special-education teacher, etc.

In general, do not hyphenate words with prefixes and suffixes (non, pre, wide, etc.).

• Examples: nonresident, prearrange, campuswide

Hyphenate to avoid triple consonants and double vowels.

• Examples: pre-election, pre-establish, pre-existing, pre-eminent
• Exceptions: cooperate, coordinate

Hyphenate if the word that follows a prefix begins with a capital letter.

• Examples: un-American, mid-March

Vertical Lists

Use vertical lists for lists that are long or contain items on several levels.

Use vertical lists for quick-reference items or for visual prominence.

Use numbers when items on a list follow a specific order.

Use bullets as visual markers for each item.

If the introductory statement is a complete grammatical sentence, end it with a colon. List items do not begin with capital letters and do not carry closing punctuation unless they are complete sentences.

• Example: Include the following documents in your application:
  • completed application
  • personal essay
  • three letters of recommendation

If the introductory statement is not a complete sentence, use the punctuation mark that's appropriate for the context (comma, semicolon, dash, or nothing). List items do not start with capital letters and have no closing punctuation.

• Example: The final report outlined the company’s
  • increased fundraising efforts
  • stabilized employee retention
  • increased recruitment efforts

Numbered Lists

Numbered items begin with a capital letter.

Do not use closing punctuation unless the item is a complete sentence.

Series

Separate items in a series with a comma. Do not use a comma before the conjunction.

• Example: The students came from California, Colorado, Maryland and Nebraska.

If the series contains lengthy elements or elements that require separation with a comma, use semicolons to avoid confusion. Use a semicolon before the conjunction in a series.

• Example: Faculty conduct research in molecular and cellular pathology and toxicology; drug delivery systems; protein structure and delivery; cancer, heart, lung and blood diseases; and alcohol and drug abuse.

Spell out numbers under 10 (one through nine).

• Example: Students were divided into four groups of nine.

Use figures for numbers 10 and up.

• Example: There was one group of 10 students.

Spell out a numeral at the beginning of a sentence.

• Examples: Nine students earned an A on the exam. Twenty-five faculty members retired this year.

Do not spell out numerals that identify a calendar year.

Decimals

Decimals should not exceed two places in textual references, except for in special circumstances.

Be consistent with the number of decimal places used—if one number has two decimal places, all numbers should have two decimal places (2.25, 2.50, etc.).

Millions and Billions

Use figures with million or billion in all uses.

• Example: More than 1 million people access the Internet every day.

Percentages

Always use numerals when referencing percentages.

• Example: Close to 9 percent of students are from foreign countries.

Spell out percent unless it is included on a quick-reference list.

In general, follow AP style.

For titles of compositions (books, movies, music, etc.), follow AP style and place in quotation marks: “Gone With the Wind,” “South Park,” “How to Save a Life”

For names of periodicals, including academic journals, follow AP style; use italics: The Denver Post, (Boulder) Daily Camera, New England Journal of Medicine

For names of articles in academic journals, use quotation marks and sentence case, rather than title case: “Characteristics of black carbon aerosol from a surface oil burn during the Deepwater Horizon oil spill” appeared in Geophysical Research Letters.

Comma

In a series or list, do not use a comma before the conjunction.

• Example: The students came from California, Colorado, Maryland and Nebraska.

Do not use a comma to separate two independent sentences; use a semicolon.

• Example: The snow started to fall during the night; the morning commute was awful.

Use a comma before a conjunction when it connects two independent sentences.

• Example: A typical master’s degree takes two years, but many universities offer accelerated master’s degree programs.

Do not use a comma before a conjunction connecting a dependent clause to an independent clause.

• Example: Some people complete their master’s degree in one year because of the program’s structure.

Colon

Use a colon to introduce lists.

• Example: Include the following documents in your application: completed application, personal essay and three letters of recommendation.

Capitalize the words immediately following the colon only if it is the beginning of a complete sentence or proper noun.

• Example: The professor promised this: If every student earned a B on the exam, there would be no final report due at the end of the semester.

Use a colon to introduce long quotes.

Do not use a colon with a verb. 

• Example:
    (Incorrect) Admission requirements are:
    (Correct) Admission requirements: -or- The admission requirements are as follows: 

Semicolons

Use a semicolon in a series or list when items in the series are long or contain material that must be set apart by commas.

• Example: Faculty conduct research in molecular and cellular pathology and toxicology; drug delivery systems; protein structure and delivery; cancer, heart, lung and blood diseases; and alcohol and drug abuse.

Use a semicolon to connect two independent sentences without a conjunction.

• • Example: The paper is due next week; she submitted it today.

Dashes

Use an em dash (longer) to mark a break in thought.

• Example: He will travel to Europe this summer – if he passes all of his classes. Insert space on each side of the em dash.

Use an en dash (shorter) to indicate a range (it replaces the word through).

• Example: 1–10. Do not insert spaces on either side of dashes.

Hyphens

See the hyphenation [5] section in this style guide for usage and rules.

Periods

Use a period at the end of a sentence.

Quotation Marks

Punctuation always goes inside quotation marks.

• Example: Professor Smith said, “Classes are canceled next week.”

email is no longer hyphenated

Internet is a proper noun and is capitalized

• Example: There are many options for students interested in drawing (e.g., art, graphic design and architecture).

Just / Only / Precisely
 Avoid ‘just’ because of its secondary meaning as ‘rightful.’ Preferred use is ‘only’ when meaning a mere amount; ‘precisely’ when meaning exact.

• Examples: He published his first book when he was only 16 years old. That is exactly why she decided to attend CU-Boulder.

In general, ask yourself whether the sentence can stand go without the adverb.

• Stronger: He published his first book when he was 16 years old. That is why she decided to attend CU-Boulder.

More Than / Over
In 2014, the Associated Press Style Guide began allowing for the use of "over" when referring to numerals and amounts, where previously it was only allowed when describing the state of being  physically "above" something. The previously preferred use of "more than" is still desireable. 

• Example: More than 60 students failed the exam.

Use over when referring to spatial relationships

• Example:  The car drove over the bridge.

That / Which
Use that in essential clauses—those that are important to the meaning of the sentence—without commas.

Use which with nonessential clauses and set off the clause with commas.

• Example: Professor Smith administered a pop quiz today, which prompted groans from all of the students.

Who / Whom
Use who as a pronoun referencing humans and animals with a name. It is never the object of a sentence, phrase or clause.

• Example:  Who is the guest of honor at the award ceremony?

NOTE: Use who when you could replace it with he or she: Who is the guest of honor? He is the guest of honor.
Use whom when someone is the object of a verb or preposition

• Example:  With whom will you be attending the dinner?

NOTE: Use whom when you could replace it with his or her: With whom will you be attending the dinner? I’ll attend the dinner with her.

Trademark and Registered Marks
