AMA Citation Style: A High School Guide

Citing sources lets readers find your information and avoids plagiarism. High school papers most often use MLA (for literature/humanities) or APA (for sciences) style bibliography.com, clearvoice.com. AMA (American Medical Association) style is a numeric citation style used in medical and health-science writing clearvoice.com, mybib.com. In AMA, sources are numbered and placed in a reference list at the end of the paper, rather than by author name. This guide explains AMA format in simple terms and shows how it differs from MLA/APA.

Key Features of AMA Style

• Numbered in-text citations: In AMA, each source is given a number (1, 2, 3, …). You insert that number in superscript in your text where you use the sourcescribbr.com. For example: “Recent studies show this is effective.^1”

• Single reference list, end of paper: All sources cited in the text are listed together at the end of the paper under a “References” heading. Entries are ordered by appearance in the text, not alphabeticallyevansville.edu. The first source you cite is #1, the second is #2, and so on.

• Reuse the same number: If you cite the same source again later, you use the same original number. You may add a page number if needed (e.g. ^1(p23) to point to a page)evansville.eduscribbr.com. You do not give it a new number.

• No author-year in text: Unlike APA (author, year) or MLA (author, page), AMA does not include the author’s name or date in the text citation. You only use the citation numberscribbr.combibliography.com.

• Punctuation: Place the citation number immediately after the relevant word or punctuation. For example, a sentence-ending citation looks like “… was confirmed.^2”scribbr.com. If mentioning a page, use superscript like this: Smith showed this effect^3(p12)scribbr.com.

• Examples: Scribbr explains: “An AMA in-text citation consists of the number of the relevant reference on your AMA reference page, written in superscript” at that point in the textscribbr.com.

Formatting the Reference List

At the end of your paper, list all cited sources in numerical order. Each entry should include enough information for a reader to locate the source. Key elements of AMA references are:

• Books: Author(s) (last name and initials). Book Title. Edition (if not first). Publisher; Year. (Do not write “1st ed.”. For more elements seeevansville.edu.)

  • Example: Smith AB, Jones CD. Fundamentals of Science. 3rd ed. Big Publisher; 2020.

• Journal Articles: Author(s). Article title. Abbreviated Journal Title. Year;Volume(Issue):Page numbers. For exampleevansville.edu:
  Brown EF, Clark GH. New findings in biology. J Med Res. 2021;45(2):123-130.

• Website/Online: Author(s). Title of page [Internet]. Year [cited YYYY Mon DD]. Name of Website. Available at: URL. (Add “Accessed” date if required.) University guides note including “Available at:” and date accessed for web sourcesevansville.edu.

Each reference entry ends with a period. Note AMA journal names are often abbreviated (e.g. JAMA for Journal of the American Medical Association). Consult an AMA manual or style guide for abbreviations.

Comparison: AMA vs. APA vs. MLA

AMA style is quite different from APA and MLA. Here are the key contrasts:

• In-Text Citations: AMA uses numbers (superscript)scribbr.com. APA uses author–date (e.g. Smith 2021) and MLA uses author–page (e.g. Smith 23)bibliography.com. For example:

  • AMA: “This is effective.^1”

  • APA: “This is effective (Smith, 2021).”

  • MLA: “This is effective (Smith 23).”bibliography.com.

• Reference List Order: AMA list is in citation order (by number)evansville.edu. APA and MLA lists are alphabetical by author. (When in doubt, follow the instructions of your teacher or style manual.)

• Author Names: AMA, like APA, uses only initials for first names (no full first names)evansville.edu. MLA uses full first names.bibliography.com. For example, an author might appear as Smith AB in AMA/APA, but Smith, John B. in MLA.

• Title Capitalization: In AMA (and APA), titles of articles/books use sentence-style capitalization (only the first word and proper nouns capitalized)evansville.edubibliography.com. MLA uses title-style capitalization (capitalize all major words)bibliography.com. Example book title:

  • AMA/APA: Chaos: a look at the stars.bibliography.com

  • MLA: Chaos: A Look at the Stars.bibliography.com.

• Final Punctuation: AMA style entries always end with a period. MLA entries always end with a period. APA entries end with a period unless the entry ends in a URL or DOIbibliography.com. (If there is a DOI or URL, APA omits the final periodbibliography.com.)

• Usage by Field: MLA is most common in high schools and humanities, APA in college-level sciences, and AMA in medicine/healthbibliography.comclearvoice.com. For example, MLA is often used for English/literature papers, APA for biology or psychology, and AMA for health-science reports. A citation guide notes: “MLA is more commonly used than APA at the high school level… MLA format is used for humanities… APA is used for scientific and technical works.”bibliography.com. MyBib explains that AMA style “is a variation of the Vancouver style… used in [AMA] publications (like JAMA)”, and that if you are in a health/medical field you will likely use AMA formatmybib.commybib.com.

When to Use AMA Style

In high school, AMA style is less common unless you are doing a health or science project where your teacher specifically requires it. However, understanding AMA can prepare you for college or professional work in health/medicine. Remember that your teacher might ask for MLA or APA instead — always check the assignment instructions. As one guide advises: “Follow your teacher’s instructions on which style to use when writing your school paper.”bibliography.com.

In summary, AMA style uses numbers in superscript with a numbered reference list ordered by appearanceevansville.eduscribbr.com. This is different from MLA and APA, which use author names in-text and alphabetized listsbibliography.combibliography.com. Learning AMA involves memorizing its formatting rules for books, articles, and websites, but the key idea for a high schooler is that citations are numbered, not author-date.

Key Points at a Glance:

• AMA = numbers in text (e.g. ^1) with a numbered References listscribbr.comevansville.edu.

• APA/MLA = author’s name in text (APA adds year, MLA adds page)bibliography.com.

• Lists: AMA = order cited; APA/MLA = alphabetical by author.

• MLA for humanities, APA for science, AMA for medical/healthbibliography.commybib.com.

By following AMA style’s guidelines and comparing them to MLA/APA, you can correctly cite sources in any assignment. Always use a credible style guide (like the AMA Manual of Style or university resources) for detailsclearvoice.comevansville.edu.
