Two Reporters. Same Story. Two Very Different Sentences.

Last chapter, you sharpened your grammar skills.

Subject-verb agreement. Tense errors. Pronoun problems. Punctuation and capitalization.

You can now spot all four in a sentence — and fix them fast.

Here's a new situation to think about. Two reporters cover the same school event. Here's what they write.

Reporter 1: "The contest was held on April 10th at 2:00 p.m. and eight students joined."

Reporter 2: "The contest was held on April 10 at 2 p.m. and 8 students joined."

Same event. Same facts. But the sentences look different. Which one is correct?

In journalism, Reporter 2 is right.

You might be wondering — why does it matter? Both sentences are clear. Both have correct grammar. What's the difference? The difference is called AP Style — and it's the reason professional news stories all look and feel consistent, no matter who writes them.

So, What Is AP Style?

AP Style is a set of writing rules used by journalists to keep news stories consistent, clear, and professional.

AP stands for Associated Press — a major international news organization that created these rules. Journalists all over the world follow AP Style so that every news story uses the same format for numbers, dates, titles, time, names, and more.

For Filipino school journalists, AP Style is especially important because it's tested in journalism competitions — including the National Schools Press Conference (NSPC). Knowing the rules gives you a real advantage.

AP Style Rule 1: Numbers

This is one of the most commonly tested AP Style rules. Get this right and you'll catch a lot of errors!

Numbers 1 through 9
❌ Wrong:"The Science Club planted 8 trees."
✅ Correct:"The Science Club planted eight trees."

Numbers one through nine are always written in words — not digits.

Numbers 10 and above
❌ Wrong:"There were twenty students in the group."
✅ Correct:"There were 20 students in the group."

Once you hit 10, use the numeral digit.

Ages & Percentages
❌ Wrong:"The nine-year-old student won first place." / "Ninety % of students came."
✅ Correct:"The 9-year-old student won first place." / "90 percent of students came."

Ages always use digits. Percentages always use digits, and the word "percent" is spelled out instead of using the "%" symbol.

Sentence Starters
❌ Wrong:"25 students joined the contest."
✅ Correct:"Twenty-five students joined the contest."

Never start a sentence with a digit! Spell it out, or rewrite the sentence so the number doesn't come first.

Grades & Scores
❌ Wrong:"The Grade four class won by two points."
✅ Correct:"The Grade 4 class won by 2 points."

Grade levels, scores, vote counts, and measurements always use digits — even if under 10.

Fractions
❌ Wrong:"About 1/2 of the books were damaged."
✅ Correct:"About half of the books were damaged."

Simple fractions below one are spelled out in words (e.g., "half", "one-third").

AP Style Rule 2: Dates

Dates come up in almost every news story. Here is how AP Style standardizes them.

Month Abbreviations (With dates)
❌ Wrong:"The program happened on January 5th."
✅ Correct:"The program happened on Jan. 5."

Abbreviate months with 6 or more letters (Jan., Feb., Aug., Sept., Oct., Nov., Dec.) when listed with a specific date. Never abbreviate short months (March, April, May, June, July).

Months Alone
❌ Wrong:"The exam is scheduled for Nov."
✅ Correct:"The exam is scheduled for November."

Never abbreviate the month if it stands alone without a specific date day.

Ordinal Suffixes
❌ Wrong:"Classes resumed on August 15th, 2026."
✅ Correct:"Classes resumed on Aug. 15, 2026."

Never use "th", "st", "nd", or "rd" after a date number. Just write the plain digit.

AP Style Rule 3: Time

Formatting Time
❌ Wrong:"The seminar starts at eight o'clock in the morning / 8:00 AM."
✅ Correct:"The seminar starts at 8 a.m."

Always use digits for time. Use lowercase "a.m." and "p.m." with periods. Drop the ":00" for round hours.

Noon & Midnight
❌ Wrong:"The lunch break starts at 12:00 p.m."
✅ Correct:"The lunch break starts at noon."

Always write "noon" and "midnight" as lowercase words — never "12 p.m." or "12 a.m."

AP Style Rule 4: Titles

Titles Before Names
❌ Wrong:"We met principal Santos yesterday."
✅ Correct:"We met Principal Santos yesterday."

Capitalize formal titles when they come directly before a person's name.

Titles After Names
❌ Wrong:"Santos, the Principal, approved the budget."
✅ Correct:"Santos, the principal, approved the budget."

Lowercase titles when they come after a name or stand alone.

Title Abbreviations
❌ Wrong:"Doctor Santos / Mister Cruz spoke."
✅ Correct:"Dr. Santos / Mr. Cruz spoke."

Abbreviate Doctor (Dr.), Mister (Mr.), Married Woman (Mrs.), and Ms. before names.

AP Style Rule 5: Names and Second Reference

First vs Second Reference
❌ Wrong:"First reference: Reyes announced it. Second: Principal Reyes said..."
✅ Correct:"First: Principal Maria Reyes announced it. Second: Reyes said..."

Use a person's full name and title on the first reference. On all subsequent references, use only the last name without any titles or courtesy tags (no Mr./Mrs./Ms.).

AP Style Rule 6: Quotations

Quotes & Attributions
❌ Wrong:"Principal Reyes exclaimed, 'We are ready.' " / "'We are ready,' Principal Reyes announced."
✅ Correct:" 'We are ready,' Principal Reyes said."

Always use the neutral attribution verb "said" rather than "exclaimed", "commented", or "stated". The attribution should follow the quote, separated by a comma inside the quotation marks.

AP Style Rule 7: Organizations and Acronyms

Handling Acronyms
❌ Wrong:"Students are preparing for the NSPC." (On first reference)
✅ Correct:"Students are preparing for the National Schools Press Conference (NSPC)."

Always spell out the full name of an organization on the first reference, introducing the acronym in parentheses. Use the acronym alone on all subsequent mentions.

AP Style Rule 8: Seasons and Academic Terms

Academic Phrasing
❌ Wrong:"The First Quarter started last Summer."
✅ Correct:"The first quarter started last summer."

Seasons (spring, summer, winter, fall) and school academic terms (first quarter, semester, school year) are always written in lowercase.

AP Style Rule 9: Addresses and Locations

Locations & Places
❌ Wrong:"The writer is from Q.C., Phils."
✅ Correct:"The writer is from Quezon City, Philippines."

Always spell out city, province, and country names in full. Avoid abbreviations like "Q.C." or "Phils."

AP Style Rule 10: Abbreviations & Capitalization — Final Rules

No All-Caps & No Day Abbreviations
❌ Wrong:"The event on Fri. is VERY important."
✅ Correct:"The event on Friday is important."

Never abbreviate days of the week (always write "Friday", "Monday"). Do not use ALL CAPS for emphasis in news stories; let the facts speak for themselves.

Rule Category What to Remember
Numbers 1–9 Spell out — eight, three, one
Numbers 10 and above Use digits — 10, 25, 300

Noon and Midnight Write as words — never write 12 p.m. or 12 a.m.
