Parents or Parent’s: Which Is Correct?

Parents is the plural of parent — more than one mother or father. Parent’s is the singular possessive — something belonging to one parent. So if you are talking about several parents at once, write parents; if something belongs to a single parent, write parent’s. (There is also a third form, parents’, the plural possessive — something belonging to several parents — which we cover below.)

Parents, Parent’s, Parents’: The Three Forms at a Glance

All three spellings are correct words; they just do different jobs. The apostrophe’s position tells you which job:

Form	Job it does	Example	Verdict
parents	Plural — more than one parent	Many parents work from home now.	Correct
parent’s	Singular possessive — belonging to one parent	A parent’s consent is needed for the trip.	Correct
parents’	Plural possessive — belonging to several parents	The parents’ association meets monthly.	Correct

The rule behind this is not a special case for parent — it is the standard English possessive system, stated the same way by the major grammar references. Cambridge’s grammar guidance says it plainly: show possession with an apostrophe + s after the noun, and when the noun is plural, put the apostrophe after the s. The Collins Dictionary language notes spell out the full pattern: add ’s to singular words (a baby’s pushchair), add ’s to plural words that don’t end in s (children’s games), and add an apostrophe alone to plural words already ending in s (your parents’ parents — Collins’s own example). Cambridge also lists a typical error worth remembering: we don’t use ’s with plural nouns. So parents, the plural, takes no apostrophe at all.

When to Use “Parents” (Plural, No Apostrophe)

Use parents whenever you mean more than one parent and nothing belongs to anyone. The plural is formed by adding s to parent — parent is a standard countable noun, so it follows the ordinary rule with no exception.

• Both of my parents are teachers.
• The school invited all parents to the open evening.
• Many parents prefer the early pick-up slot.

The mistake to avoid here is the stray apostrophe: ✗ The parent’s arrived at noon would mean “the parent is arrived,” and ✗ Many parent’s were present is simply wrong — an apostrophe never marks a plain plural. This is the error the Collins test is designed to catch: the boy’s books means one boy owns the books, while the boys’ books means several boys do. The apostrophe’s position answers one question: who is the owner, and how many of them are there? If there is no owner at all, there should be no apostrophe at all.

When to Use “Parent’s” (Singular Possessive)

Use parent’s when something belongs to, relates to, or is associated with one parent. The singular noun takes ’s, exactly as it would for any singular noun (a baby’s pushchair, Hannah’s book).

• We need a parent’s signature on the permission slip. (one parent signs)
• Each child was picked up by his or her parent’s carer. (one parent’s carer)
• The parent’s evening was scheduled for Thursday. — but read the next section before you write this one.

That last example is where people most often trip. A school event that all parents attend is not really the evening of one parent, which is why the plural possessive parents’ is the standard spelling for it (more on that below). The singular possessive only fits when one specific parent is the owner — my parent’s phone, a parent’s complaint about a single complaint from a single parent.

Don’t Forget “Parents’” (Plural Possessive)

Searches for “parents or parent’s” are usually missing the form people actually need most: parents’, the plural possessive. Because parents already ends in s, English adds just a lone apostrophe after it — parents’ — rather than another s. You need this form whenever something belongs to parents in general, or to several parents at once:

• We stayed at my parents’ house. (the house of both parents)
• Tonight is the school’s parents’ evening. (the evening for the parents — UK schools standardly write it this way)
• The parents’ committee approved the budget. (a committee of several parents)
• I’m sure my views on marriage are coloured by my parents’ divorce. (an actual usage example recorded in the Cambridge Dictionary’s grammar notes)

Compare the three possessive-ish spellings on the word parent to feel the logic: parent’s (one parent owns), parents’ (several parents own). Before the s = one owner; after the s = many owners. The meaning changes entirely with that apostrophe’s position, which is why getting it right is worth the moment of thought.

Correct vs Incorrect: Real Examples

Most real-world mistakes come from using the singular possessive parent’s where the plural or plural possessive is meant. Run through these:

Incorrect	Correct	Why
✗ Both parent’s attended.	✓ Both parents attended.	More than one parent, no possession — plain plural, no apostrophe.
✗ The parent’s evening is Thursday.	✓ The parents’ evening is Thursday.	The evening is for all the parents, so the plural possessive is the standard form.
✗ We drove to my parent’s house.	✓ We drove to my parents’ house.	The house belongs to both parents (in the usual reading), not one.
✗ The schools asks parents to sign.	✓ The school asks parents to sign.	Two errors for one: plural of parent and plain subject school take no apostrophes.
✗ A parents consent is required.	✓ A parent’s consent is required.	Here one parent gives consent, so the singular possessive is right.
✗ The parent’s met the teachers.	✓ The parents met the teachers.	Several parents meeting — plural, no owner, no apostrophe.

The Two-Question Test

When you are unsure, borrow the test Collins suggests for apostrophe placement and ask two questions, in this order:

1. Is anything owned or possessed? If not — if you just mean several parents — write parents with no apostrophe. Stop there.
2. How many owners are there? One parent owns it: parent’s (apostrophe before the s). Several parents own it: parents’ (apostrophe after the s).

Try it on a tricky one: “___ permission is required.” Is anything owned? Yes — the permission belongs to someone. How many owners? One parent’s permission is required — so A parent’s permission is required. Now try: “The ___ association voted.” One parent, or all of them? An association is made up of several parents — The parents’ association voted.

FAQs

Is it “parent’s day” or “parents’ day”?

If you mean a day celebrating both parents — the usual sense, and the US observance established by Congress in 1994 is spelled Parents’ Day — use parents’. Parent’s Day would mean a day belonging to one parent, which is rarely what is meant.

Should I write “parents evening” or “parents’ evening”?

Parents’ evening, with the apostrophe after the s. It is the evening for the school’s parents collectively — a plural possessive. This is the standard spelling in UK education; parents evening without the apostrophe is common but less careful, and parent’s evening wrongly suggests the event belongs to a single parent.

Can “parent’s” ever be a plural?

No. Parent’s with an apostrophe is a possessive — or, occasionally, a contraction of “parent is” or “parent has” (My parent’s coming to pick me up). It is never a plain plural, though. The plural of parent is always parents, with no apostrophe. Note that possessive pronouns behave differently: its, yours, and theirs show possession without any apostrophe — but parent’s is a noun, not a pronoun, so it keeps its apostrophe.

What about “parents’s”?

It does not exist as a standard form. Once a plural noun ends in s, English uses the lone apostrophe — parents’ — never parents’s. Adding another s after the apostrophe is the one pattern the grammar references rule out for regular plurals.

Is “a parents meeting” ever correct?

Not without the apostrophe. A parents meeting reads as a plural noun jammed against another noun; what you mean is a parents’ meeting — a meeting of the parents. (A “parent meeting,” singular, is also fine and common in US schools, meaning a meeting for any parent.)

The Takeaway

Parents is the plural, parent’s is the singular possessive, and parents’ is the plural possessive — and all three are correct in their own lane. The confusion almost always comes from reaching for parent’s when the sentence is really about several parents. Count the parents first, then place the apostrophe: no owner, no apostrophe (parents); one owner, apostrophe before the s (parent’s); several owners, apostrophe after the s (parents’). That single habit will get this word right every time.
