AP Spanish Passive Voice: Practice Test & Review

By SpanishGram

◄ Back to AP Grammar Hub

The passive voice in Spanish has two forms. The true passive uses ser + past participle + por to name the agent: La novela fue escrita por García Márquez. The passive se uses se + third-person verb with no agent: Se venden casas. The AP exam tests both in reading passages about history, science, and culture, and in the written free-response tasks, where a passive construction is often the cleanest way to report an event without naming who did it.

This page gives you a five-part practice quiz: an evaluation set to see where you stand, three practice sets to drill the contrast, and a challenge set to confirm mastery. Every question is built around a sentence feature that forces exactly one form: an explicit agent with por (ser + participle), no agent and a general statement (se + verb), or a subject that controls the agreement of the participle. If you get stuck, scroll down for the full grammar guide.

The Rule

The passive voice in Spanish has two forms. The true passive uses ser + past participle + por to name the agent: La novela fue escrita por García Márquez. The passive se uses se + third-person verb with no agent: Se venden casas. The true passive focuses on the action and the agent. The passive se focuses on the action alone, often as a general statement or rule. In the true passive, the past participle agrees in gender and number with the subject. The auxiliary ser is conjugated in the tense the sentence requires.

Ser + Past Participle + Por

Subject Example Translation
Singular masculine El libro fue publicado. The book was published.
Singular feminine La novela fue escrita por García Márquez. The novel was written by García Márquez.
Plural masculine Los edificios fueron construidos. The buildings were built.
Plural feminine Las canciones fueron compuestas. The songs were composed.
Agent with por La carta fue escrita por mi abuelo. The letter was written by my grandfather.

Passive Se: No Agent

Function Example Translation
General sale or availability Se venden libros. Books are sold.
General rule or prohibition Se prohíbe fumar. Smoking is prohibited.
General statement Se habla español. Spanish is spoken.
Impersonal se with human agent Se construyeron muchas casas. Many houses were built.

Common Mistakes

1. Participle not agreeing with the subject.
✗ Las casas fueron construido en 1990.
✓ Las casas fueron construidas en 1990.
The participle must agree in gender and number with the subject (casas: feminine plural).

2. Using the passive se with an explicit agent.
✗ Se escribió la novela por García Márquez.
✓ La novela fue escrita por García Márquez.
When the agent is named with por, use the true passive (ser + participle), not se.

3. Using the true passive without an agent when the sentence is a general statement.
✗ Fue prohibido fumar en este edificio. (for a general rule)
✓ Se prohíbe fumar en este edificio.
General rules and statements use the passive se, not ser + participle.

4. Wrong verb agreement in passive se.
✗ Se vende libros.
✓ Se venden libros.
In the passive se, the verb agrees with the noun that follows (libros: plural).
