An APA style outline organizes empirical studies, proposals, and dissertations before drafting prose. While researchers frequently search for an official apa format outline, the Publication Manual of the American Psychological Association (7th ed., 2020) does not mandate a rigid outline template. Instead, Section 4.26 defines outlining as a prewriting strategy to ensure logical structure and balanced arguments. When departments or instructors require an outline in apa format, the file must adhere to standard APA 7 manuscript formatting—1-inch margins, standard fonts, double line spacing, and page headers—while utilizing recognized alphanumeric or decimal conventions.
A common challenge when preparing an outline apa format is understanding how outline markers relate to narrative headings. Outlining markers organize concepts during planning, but they must never appear in final APA headings. For complete manuscript mechanics, see our guide on how to write a research paper in APA style.
Does APA 7 Have an Official Outline Format?
No single template serves as the official apa outline format. Section 4.26 of the APA 7 manual notes that outlines structure ideas and determine headings, leaving layout details to course or institutional guidelines.
When an assignment specifies an outline format apa submission, standard APA document mechanics apply:
- Margins: Exactly 1 inch (2.54 cm) on all sides.
- Typography: An approved font, such as 12-point Times New Roman, 11-point Calibri, 11-point Arial, or 11-point Georgia.
- Line Spacing: Double-space throughout the document.
- Page Headers: Arabic page numbers in the top-right header, starting on page 1. Professional papers include a running head (50 characters or fewer) flush left.
- Title Page: Standard APA student or professional title page preceding the outline.
Crucially, Section 2.27 dictates that final narrative headings must never include numbers or letters (such as "1. Method"). Outlining symbols belong strictly to planning stages and must be omitted from final manuscript headings.
Core Principles of Writing an Outline in APA Format
When organizing outlines in apa format, university writing standards—such as those codified by the Purdue University Online Writing Lab (Purdue OWL)—rely on four core principles:
- Division (Rule of Two): A heading cannot be divided into a solitary subsection. If you create an "A," you must have a "B." If you use a "1," you must include a "2."
- Coordination: Headings at the same hierarchical tier share equivalent argumentative scope.
- Subordination: Lower-tier items supply evidence or operational details supporting the parent point.
- Parallelism: Headings within each tier preserve uniform grammatical phrasing across coordinate items.
APA Outline Formats: Alphanumeric, Full Sentence, and Decimal
Writers developing an apa style format outline generally select from three recognized organizational frameworks.
Alphanumeric Outline Structure
The alphanumeric format is the standard apa format for outlines in scholarly writing, alternating characters across tiers:
- Roman Numerals (I, II, III): Primary paper sections or core arguments.
- Capital Letters (A, B, C): Major subsections or conceptual divisions.
- Arabic Numerals (1, 2, 3): Supporting empirical findings, methods, or subtopics.
- Lowercase Letters (a, b, c): Specific data points, citations, or operational measures.
Full-Sentence Outline Format
A full-sentence outline uses the alphanumeric hierarchy, but every entry forms a complete grammatical sentence. This format is ideal for thesis proposals and empirical studies because it articulates tested hypotheses. Sourced assertions require standard APA parenthetical citations (e.g., Miller & Thorne, 2023), accompanied by a formal reference list, as discussed in our guide on APA References vs. Works Cited.
Decimal Outline Format
The decimal format uses numeric notation (1.0, 1.1, 1.1.1) to show hierarchical relationships, commonly applied in quantitative reports, engineering, and experimental protocols.
Mapping Outline Levels to APA 7 Heading Levels
Linking outline tiers directly to APA 7 heading levels (Section 2.27) streamlines drafting:
| Outline Tier | APA 7 Level | Narrative Heading Style | Outline Example |
|---|---|---|---|
| I, II, III | Level 1 | Centered, Bold, Title Case | I. Method |
| A, B, C | Level 2 | Flush Left, Bold, Title Case | A. Participant Characteristics |
| 1, 2, 3 | Level 3 | Flush Left, Bold Italic, Title Case | 1. Inclusion Criteria |
| a, b, c | Level 4 | Indented, Bold, Title Case, Period | a. Cognitive Screening. |
| (1), (2) | Level 5 | Indented, Bold Italic, Title Case, Period | (1) Automated Scoring. |

Filled APA Style Outline Example (Fictional Study)
The following filled example illustrates a full-sentence outline for a fictional empirical study evaluating working memory training in undergraduate cohorts. It models proper hierarchy, the Rule of Two, parallel phrasing, and parenthetical in-text citations.
Working Memory Training and Academic Performance
Thesis: Targeted adaptive working memory training produces significant gains in working memory capacity and reading comprehension among university undergraduates compared to active controls.
I. Introduction
A. Cognitive load during academic reading poses a challenge for undergraduates.
1. Working memory capacity constrains multi-step inference generation (Miller & Thorne, 2023).
2. Traditional study strategies rarely target executive functioning directly (Aris & Vance, 2021).
B. The study evaluates an adaptive dual n-back protocol against active controls over eight weeks.
1. Hypothesis 1: Adaptive training will yield significant gains on operation span tasks.
2. Hypothesis 2: Experimental participants will achieve higher reading comprehension scores.
II. Method
A. A sample of 120 undergraduates will be recruited from a university participant pool.
1. Participants must report normal vision and no neurological history.
2. Course credit will be awarded upon completing all experimental phases.
B. Standardized cognitive instruments will quantify baseline and outcome performance.
1. The Automated Operation Span task will assess working memory capacity (α = .88).
2. The Nelson-Denny Reading Test will assess silent reading comprehension scores.
III. Anticipated Results
A. Preliminary diagnostics will verify baseline comparability across study conditions.
1. Two-sample t-tests will confirm baseline equivalence across cohorts.
2. Levene's test will evaluate homogeneity of variance across conditions.
B. A 2 × 2 mixed-model ANOVA will evaluate intervention efficacy across time.
1. An interaction between condition and session is predicted for memory scores.
2. Planned contrasts will evaluate whether memory gains mediate reading improvements.
IV. Discussion
A. Findings will clarify conditions under which cognitive training yields transfer.
1. Hypothesis confirmation will validate memory training as an academic intervention.
2. Divergent results will support domain-specific modularity models.
B. Practical implications will guide university learning center workshops.
1. Academic coaching centers can incorporate adaptive modules into curricula.
2. Constraints qualify findings to healthy undergraduate cohorts.

Checklist of Required Elements for APA Outlines
Before submitting an outline in APA format, verify this checklist:
- [ ] Document Mechanics: 1-inch margins on all sides and an approved APA font throughout.
- [ ] Header: Arabic page numbers top-right; running head on professional manuscripts.
- [ ] Title Page: Standard APA 7 title page with author and institutional metadata.
- [ ] Thesis: Explicit research objective or thesis statement preceding Section I.
- [ ] Division: Every divided level contains at least two items (an A requires a B; a 1 requires a 2).
- [ ] Coordination: Headings at the same tier share equal importance and parallel structure.

- [ ] Transition: Outline symbols (I, A, 1) prepared for removal in narrative headings.
Frequently Asked Questions
Does APA 7 require double spacing in an outline?
Yes. APA 7 specifies double-spacing throughout all paper elements. Instructors may permit single-spacing for condensed assignment grading, but double-spacing is standard.
Should outline numbers and letters appear in the final paper headings?
No. Section 2.27 of the APA 7 manual strictly prohibits numbers or letters in manuscript headings. Outline characters are temporary structural scaffolds for planning.
Do I need to cite sources in an APA outline?
Yes, if you draft a full-sentence outline citing published research or empirical findings. In-text parenthetical citations (Author, Year) and a corresponding reference list are required.
What is the difference between a topic outline and a sentence outline?
A topic outline uses short phrases to map sections quickly. A sentence outline expresses every heading and subheading as a complete, grammatical sentence with articulated arguments.
