SAT Pronouns and Possessives: Agreement, Apostrophes, and Clear Reference
Master pronouns and possessives on the digital SAT: pronoun agreement, clear antecedents, its vs it's, their vs there vs they're, apostrophes, and common reference traps.
Pronoun questions on the digital SAT usually test one of four things:
- Does the pronoun clearly refer to a specific noun?
- Does it agree with that noun in number?
- Is the correct grammatical case being used?
- Is a possessive or contraction spelled correctly?
The best rule is:
pronoun must have a clear, logical, grammatically compatible antecedent
A sentence can sound conversationally normal and still fail one of those tests.
Why this belongs to Standard English Conventions
College Board's Standard English Conventions domain includes Form, Structure, and Sense. Pronouns sit at the intersection of grammar and meaning.
Questions may test:
- singular/plural agreement;
- ambiguous reference;
- subject vs object pronouns;
- possessive pronouns;
- apostrophes;
- contractions;
- relative pronouns;
- pronoun reference across long sentences.
Pronoun and antecedent
The noun a pronoun refers to is its antecedent.
The telescope completed its first survey.
Antecedent:
telescope
Pronoun:
its
Both singular.
Worked example 1: number agreement
The researchers submitted ___ findings.
Antecedent:
researchers
Plural.
Correct:
their
not "its."
Singular "they"
Modern Standard English accepts singular "they" in many contexts, especially for an indefinite or unknown person.
Example:
Each applicant should submit their materials by Friday.
Real-world usage and style conventions have evolved. SAT questions generally avoid relying on controversial or ambiguous edge cases and instead provide a clear conventional choice based on context.
Do not apply outdated blanket rules if the sentence clearly uses accepted singular-they structure.
Clear reference
Incorrect or ambiguous:
When Maya spoke with Elena, she explained the new method.
Who is "she"?
- Maya?
- Elena?
If the intended referent matters and is not clear, a noun should replace the pronoun.
Better:
When Maya spoke with Elena, Maya explained the new method.
The SAT may test clarity even when both possible antecedents match in number/gender.
Worked example 2: ambiguous pronoun
The report compared the old method with the new model, but it was less reliable.
What was less reliable?
- report?
- method?
- model?
"it" is ambiguous.
A clearer revision names the intended noun:
...but the old method was less reliable.
Pronoun agreement with indefinite nouns
Singular nouns generally take singular reference.
The committee revised its report.
Plural nouns take plural:
The committees revised their reports.
But remember that some collective-noun and singular-they contexts can be nuanced; SAT answer choices typically make the tested agreement clear.
Subject pronouns vs object pronouns
Subject forms
- I;
- he;
- she;
- we;
- they;
- who.
Object forms
- me;
- him;
- her;
- us;
- them;
- whom.
Use the pronoun's job inside its own clause.
Worked example 3: compound subject
___ and Maya presented the findings.
Would you say:
Me presented the findings?
No.
You would say:
I presented the findings.
So:
Maya and I
not "Maya and me."
Worked example 4: compound object
The director thanked Maya and ___.
Remove "Maya and":
The director thanked me.
So:
me
not "I."
The remove-the-other-person test is fast and reliable.
Who vs whom
Who
Subject form.
Who conducted the experiment?
Whom
Object form.
Whom did the researcher interview?
In complex sentences, look at the pronoun's role in its own clause, not its position in the larger sentence.
SAT questions may test relative-pronoun structure, though "whom" appears less frequently in modern general usage.
Worked example 5: who/whom
The scientist ___ led the project presented the results.
Blank is subject of:
___ led the project.
So:
who
Its vs it's
its
Possessive:
The company revised its policy.
it's
Contraction:
it is
or sometimes:
it has
It's unusual.
= It is unusual.
Possessive "its" has no apostrophe.
Worked example 6: its/it's
The instrument lost ___ calibration during transport.
Need possession:
its
Test:
The instrument lost it is calibration...
Impossible.
So "it's" is wrong.
Their / there / they're
their
Possessive:
their results.
there
Location/existence:
The samples are there.
There are three samples.
they're
Contraction:
they are
On the SAT, substitute the expanded meaning if unsure.
Your / you're
your
Possessive.
you're
You are.
The same substitution strategy works.
Whose / who's
whose
Possessive:
the researcher whose study...
who's
Who is / who has.
Example:
Who's presenting?
= Who is presenting?
Possessive apostrophes
Singular noun
Usually add:
the scientist's notebook.
Plural noun ending in s
Usually add apostrophe after s:
the scientists' notebooks.
Irregular plural not ending in s
Add:
the children's books.
Worked example 7: singular vs plural ownership
One researcher owns the lab:
the researcher's lab.
Several researchers jointly own/use the lab:
the researchers' lab.
Apostrophe position changes the number of owners.
Possessive pronouns do not take apostrophes
Correct:
- hers;
- ours;
- yours;
- theirs;
- its.
Incorrect:
- her's;
- our's;
- your's;
- their's.
Apostrophes mark contractions or noun possession, not possessive pronouns.
Joint vs separate possession
Joint ownership:
Maya and Elena's project.
One shared project.
Separate ownership:
Maya's and Elena's projects.
Each has a project.
SAT questions usually provide enough context to determine whether possession is joint or separate.
Worked example 8: shared object
Maya and Leo coauthored one paper.
Correct:
Maya and Leo's paper.
The possessive marker can appear on the final name for joint ownership.
Pronoun reference across long sentences
The committee reviewed several proposals submitted by local organizations before announcing that they would receive funding.
Who will receive funding?
"they" could refer to:
- proposals;
- organizations;
- committee members.
A well-edited sentence should make the intended referent clear.
When ambiguity affects meaning, choose the answer that names the noun directly.
Pronouns after prepositions
Prepositions take object forms:
between you and me.
Not:
between you and I.
Likewise:
for her and him.
A common hypercorrection is choosing "I" because it sounds formal.
Use grammar, not perceived formality.
Worked example 9: between
The responsibility was divided between Ana and ___.
Remove Ana:
between me.
So:
me
Pronoun and modifier interaction
After interviewing Priya, Maya said she had changed her mind.
Even if "she" is grammatically singular, the reference may be unclear.
Pronoun correctness includes sense, not just agreement.
See SAT Modifiers for broader attachment/clarity issues.
Pronoun and subject-verb agreement interaction
Each of the researchers said that they were ready.
Depending on the intended style/context, singular "they" can refer to "each" semantically as an individual person, while the verb inside the pronoun's clause agrees with plural-form "they":
they were.
Do not confuse antecedent agreement with the grammatical agreement inside the new clause.
Demonstrative pronouns: this/that/these/those
Make sure the referent is clear.
Weak:
The experiment failed repeatedly. This frustrated the team.
"This" can refer broadly to the situation, which can be acceptable, but SAT choices may offer a more precise noun phrase:
This repeated failure frustrated the team.
Precision can improve clarity when reference is vague.
Common traps
Trap 1: pronoun matches nearby noun but not intended antecedent
Trace meaning.
Trap 2: ambiguous "it," "they," or "this"
Name the noun if needed.
Trap 3: use "I" everywhere because it sounds formal
Use subject/object case.
Trap 4: apostrophe in possessive "its"
its
has no apostrophe.
Trap 5: confuse "their" and "they're"
Expand contraction.
Trap 6: possessive pronoun with apostrophe
No: "their's."
Trap 7: apostrophe placed before/after s without checking number of owners
Determine singular vs plural first.

Final takeaway
Pronoun questions are not just "singular vs plural."
Check four things:
reference+agreement+case+possession
If the reader cannot tell exactly who or what the pronoun refers to, the sentence is not doing its job—even if the pronoun form itself looks grammatical.
