You've done the hard part. Your paper is written, your sources are cited, and your references are in order. Now it's time to make sure everything is polished and ready to submit.
Let's go through a few final checks that catch the small mistakes that make a big difference.
1. Check your formatting
Make sure your paper follows the basic APA formatting rules. If you used PERRLA, you can rest easy: this was all handled from the start. If not, check for:
- One-inch margins on every side of the page
- Double spacing throughout, the references page included
- A legible, APA-approved font, like 12-point Times New Roman or 11-point Calibri
- Page numbers in the top right corner
- The right items on your title page, for APA and for anything your professor adds
- The right heading levels, if you used headings
- A references page that starts on a new page
2. Proofread your writing
Even the best ideas get lost in confusing writing or a pile of errors. Read your paper slowly, or better yet, read it out loud, to catch awkward phrasing, grammar mistakes, and run-on sentences.
You can also ask someone else to read it. A fresh set of eyes catches things you've missed. Many schools have writing centers that are a huge help when you plan ahead and leave yourself time to use them.
3. Double-check your in-text citations
- Does every quote, paraphrase, or borrowed idea have a citation?
- Do the citations match your reference list, names and dates included?
- Does every direct quote have its page number?
- Are the citations inside the sentence's final punctuation, except after a block quote?
A missing or wrong citation can turn into plagiarism, even when it was unintentional.
And if a reference on your list isn't cited anywhere in your paper, take it off the references page.
4. Review your reference list
- Is every source you cited in your paper on the list?
- Are the references in alphabetical order, by the first author's last name?
- Is each reference formatted correctly: punctuation, italics, capitalization, and spacing?
- Does every reference have a hanging indent?
Small details like periods, commas, and capital letters are easy to miss, but they're all part of the APA format.
5. Don't forget your professor's instructions
Sometimes your professor asks for something different from what APA requires, and that's their call. Your professor's preferences always come first, so follow any specific instructions they've given for the assignment.
That's it. A few extra minutes with these checks helps you avoid simple mistakes and makes your work as strong as it can be.

Bigfoot: The Truth Revealed
Bigfoot has been reported across western North America for decades, yet no body has ever been authenticated. Hair offered as proof keeps matching animals we already know (Sykes et al., 2014), and the pattern goes back to a 1977 test that traced one sample to the deer family (Federal Bureau of Investigation [FBI], n.d.).
