Hong KongSemicolons, colons and dashes
A semicolon joins two independent clauses. A colon introduces a list, an explanation or a quotation after a complete sentence. A dash sets off an interruption. The semicolon is the one the exam relies on, because it is the legal alternative to the comma splice.
Three marks that people use interchangeably and the exam does not.
One test each
| Mark | Job | Test |
|---|---|---|
| Semicolon | Joins two independent clauses | Could a period go here? If yes, a semicolon can |
| Colon | Introduces what follows | Is everything before it already a complete sentence? |
| Dash | Sets off an interruption or a sharp aside | Could commas or parentheses do the same job? |
The period test for a semicolon is exact. A semicolon is legal in precisely the places a period is legal, and it says the two thoughts belong together.
The colon rule people break
What comes before a colon has to be a complete sentence. That is the whole rule and it eliminates most wrong options instantly.
Wrong: "The materials needed are: pens, paper, and folders." The materials needed are is not a sentence.
Right: "You will need three things: pens, paper, and folders." You will need three things stands on its own.
This is the single most reliable punctuation check on the subtest. Cover everything after the colon and read what is left.
The semicolon in a complex list
There is a second use, and it is the one that turns up in test items about schedules and rosters. When the items in a list already contain commas, separate them with semicolons instead.
"The team includes Ms. Ruiz, sixth grade; Mr. Adler, seventh grade; and Ms. Chen, eighth grade." Commas inside the items, semicolons between them. Without that, the sentence lists six things instead of three.

Dashes, briefly
A pair of dashes can replace a pair of commas around a nonessential element, and a single dash can introduce an abrupt addition at the end of a sentence. Both are correct English.
They are unlikely to be the focus of an item, because a dash is usually optional where a comma or a colon would also work, and a well-built question needs one defensible answer. If you see a dash in an option, check whether the sentence would be equally correct with commas. If it would, the dash is probably not what the question is about.
You will not find an em dash anywhere on this site. It is the most reliable single tell that a machine wrote a sentence, and we replace every one with a plain hyphen. That is our editorial policy rather than a rule of English, and the exam has no view on it.
What to actually memorize
- Semicolon equals period. Both sides must stand alone.
- Colon needs a complete sentence in front of it.
- Semicolons separate list items that already contain commas.
- A conjunctive adverb such as however takes a semicolon before and a comma after.
Four lines. That is genuinely the whole topic at the level a 30-question subtest can test it, and punctuation is one skill of the twelve under Competency 3. Learn the four, then go and work on pronouns, which get four skills to punctuation's one.
Common questions
When do I use a semicolon instead of a comma?
When both sides of the join could stand as sentences. A comma alone between two independent clauses is a comma splice; a semicolon is one of the four legal fixes for it. The other three are a period, a comma plus a conjunction, and subordination.
What has to come before a colon?
A complete sentence. "You will need three things: pens, paper, and folders" is correct because the words before the colon stand alone. "The materials needed are: pens" is wrong, because that opening is not a sentence.
When do semicolons appear inside a list?
When the individual items already contain commas. Separating them with semicolons keeps the boundaries clear, so "Ms. Ruiz, sixth grade; Mr. Adler, seventh grade" reads as two people rather than four items.
Are dashes tested on the FTCE?
Rarely as the focus of an item, because a dash is usually interchangeable with commas or a colon and a good question needs one defensible answer. Skill 11 covers standard punctuation generally, so a dash can appear inside an option without being the point.
