SIOP Review and Assessment: Closing the Loop on Every Lesson

Review and Assessment is the eighth and final component of the SIOP framework, and it brings the instructional cycle full circle. If Lesson Preparation (Component 1) asks “Where are we going?” then Review and Assessment asks “Did we get there?” This component challenges teachers to provide a comprehensive review of key vocabulary and content, give students regular feedback, and use ongoing assessment to take the pulse of the class throughout every lesson—not just at the end.

For English Learners, review and assessment serve a dual purpose. They reinforce the content students have learned and they reinforce the language students have practiced. A student who encounters a key vocabulary term during building background, uses it during interaction, applies it during practice, and then reviews it at the end of the lesson has had multiple exposures to that term across the lesson. That kind of deliberate recycling is what moves vocabulary from short-term memory into lasting acquisition.

In the SIOP model, Review and Assessment refers to the instructional practices teachers use to revisit learning objectives, reinforce key vocabulary and content concepts, provide actionable feedback, and gather data on student understanding. It is not a single end-of-lesson quiz. It is a continuous process that happens throughout instruction.

SIOP breaks Review and Assessment into four features: giving a comprehensive review of key vocabulary (Feature 27), giving a comprehensive review of key content concepts (Feature 28), providing regular feedback to students on their output (Feature 29), and conducting assessment of student comprehension and learning of all lesson objectives throughout the lesson (Feature 30). The fact that SIOP separates vocabulary review from content review is a deliberate reminder that language deserves the same attention as content—all the way through to the end of the lesson.

This feature asks teachers to dedicate time at the end of the lesson—and at strategic points throughout—to review the key vocabulary terms students have been learning. This is not a quick “Does everyone remember what evaporation means?” It is a structured activity where students actively engage with the vocabulary: using it in sentences, matching terms to definitions, explaining terms to a partner, or categorizing vocabulary in a graphic organizer.

For English Learners, vocabulary review is essential because word learning requires multiple exposures in multiple contexts. Research suggests students need to encounter a new word six to twelve times before it moves into long-term memory. A comprehensive vocabulary review at the end of a lesson provides one more critical exposure—and when that review involves students actively producing the language (not just recognizing it), the impact on retention is even greater.

Parallel to vocabulary review, this feature focuses on reviewing the content concepts of the lesson. Did students grasp the main ideas? Can they articulate the key takeaways? A comprehensive content review might involve students summarizing the lesson’s main points with a partner, completing an exit slip that addresses the content objective, or participating in a whole-class review activity like numbered heads together or a gallery walk of student work.

When there is not time for a comprehensive review, it may be a signal that the lesson tried to cover too much. Review is just as important as Building Background—it bookends the lesson and gives students an opportunity to consolidate their understanding and assess their own development. Skipping it or rushing through it undermines everything that came before

Feedback is the mechanism through which students understand what they are doing well and what they need to improve. In the SIOP framework, feedback is not limited to grades on assignments. It includes verbal feedback during collaborative activities (“I noticed you used cause-and-effect language in your explanation—great work”), written feedback on student work, and self-assessment opportunities where students evaluate their own progress toward the lesson’s objectives.

For English Learners, feedback on language use is particularly important. A student may understand the content perfectly but struggle to express it in academic English. Feedback that acknowledges the content understanding while also providing a language scaffold (“Your explanation of photosynthesis was accurate. Try using the sentence frame ‘The process involves…’ to make it sound more academic”) supports both content and language growth simultaneously.

A teacher’s number one job is to take the students’ pulse and use that data to determine the next best step. This requires ongoing assessment that is rigorous, transparent, and efficient. Teachers cannot afford to wait until the end of the lesson—or worse, until the end of the unit—to find out whether students understand the material. They need real-time data gathered throughout instruction.

Effective formative assessment techniques for SIOP classrooms include quick comprehension checks like thumbs up/thumbs down, whiteboards where students write brief responses that the teacher can scan instantly, think-pair-share where the teacher listens to partner conversations, exit slips that take just two minutes to complete, and fist-to-five self-assessment where students rate their own understanding on a scale. Each of these gives the teacher immediate, actionable data without interrupting the flow of instruction.

English Learners face a unique assessment challenge: it can be difficult to determine whether a student does not understand the content or simply lacks the English to demonstrate understanding. Effective SIOP review and assessment addresses this by providing multiple ways for students to show what they know—through speaking, writing, drawing, gesturing, demonstrating, or using their home language as a bridge.

Providing students with a review and giving them feedback on their progress empowers them in multiple ways. It gives them a chance to solidify their learnings. It offers them a chance to notice their successes and challenges with both the language and the content. And it helps them understand that the process of learning is a matter of conscious competence—moving from not knowing what you don’t know, to knowing what you don’t know, to consciously practicing, to mastery.

A 3rd-grade teacher is closing a lesson on animal adaptations. She begins her review by asking students to turn to a partner and use three vocabulary terms from the lesson (adaptation, camouflage, habitat) in a complete sentence about an animal they studied. She listens to several pairs and provides quick verbal feedback: “I love how you used ‘habitat’ to explain where the arctic fox lives. Can you add why its white fur is an adaptation for that habitat?”

Next, she distributes an exit slip with two prompts: “Name one adaptation and explain how it helps an animal survive” and “Rate your understanding of today’s lesson from 1 to 5.” As students complete them, she sorts the exit slips into three piles: got it, almost there, and needs reteaching. She uses the “needs reteaching” pile to plan a small-group review session for the following day. In five minutes, she has reviewed vocabulary, reviewed content, provided feedback, and assessed comprehension—all four features of SIOP Review and Assessment in action.

Q: What is SIOP Review and Assessment?

A: SIOP Review and Assessment is the eighth and final component of the SIOP framework. It involves reviewing key vocabulary and content, providing regular feedback, and using ongoing formative assessment to monitor student understanding throughout every lesson.

Q: Why does SIOP separate vocabulary review from content review?

A: SIOP separates vocabulary review (Feature 27) from content review (Feature 28) to reinforce that language deserves the same attention as content throughout the entire lesson cycle. For English Learners, vocabulary is often the biggest barrier to comprehension, so it warrants its own dedicated review.

Q: What are effective formative assessment techniques for English Learners?

A: Effective techniques include thumbs up/thumbs down, whiteboards for quick written responses, think-pair-share with teacher monitoring, exit slips, fist-to-five self-assessment, and graphic organizers that students complete during the lesson. The key is gathering real-time data without interrupting instructional flow.

Q: How often should teachers assess during a SIOP lesson?

A: SIOP calls for ongoing assessment throughout the lesson, not just at the end. Teachers should be taking the pulse of the class at multiple points—after building background, during interaction activities, and during practice and application—to gather real-time data and adjust instruction as needed.
