What Is the Read and Complete Question?
Read and Complete is one of 19 question types on the Duolingo English Test (DET). You're shown a short passage — usually 70–110 words — with several words missing their last few letters. Your job is to type the missing letters so each word is spelled correctly and makes sense in context. The title, the first sentence, and the last sentence of the passage are always shown complete; only words inside the middle sentences are ever turned into blanks.
It's an adaptive question type, which means the difficulty of the next Read and Complete passage you see depends on how well you did on the last one. If the passages start feeling noticeably harder partway through the test, that's actually a good sign — it means you're doing well.
| Detail | Answer |
|---|---|
| Appearances on test | 3–6 times, during the Comprehension section |
| Time given | 3 minutes per passage |
| What's shown complete | Title, first sentence, last sentence — always |
| What's blanked | Selected words inside the middle sentences (partial letters removed) |
| Question format | Adaptive — difficulty shifts based on your recent accuracy |
| Subscores affected | Literacy and Comprehension |
| Scoring per word | Partial credit — each word is scored individually, not pass/fail for the whole passage |
| Input quirk | Arrow keys don't move the cursor between blanks — click or tab instead |
Why Read and Complete Feels Harder Than It Should
Most test-takers rate Read and Complete as one of the more stressful question types on the DET — not because it demands advanced vocabulary, but because the format is unfamiliar. Nobody grows up filling in half-erased words against a countdown timer. The good news: once you know the mechanic, the difficulty drops fast, because the passage itself is almost always doing more of the work than it looks like at first glance.
A first-time test-taker sees a wall of broken words and panics. A prepared test-taker sees a passage where the title and two full sentences are already handed to them for free, and where several of the "missing" words are quietly spelled out somewhere else in the same passage.
What Read and Complete Is Actually Testing
Read and Complete feeds into two subscores:
| Subscore | What It Reflects Here |
|---|---|
| Literacy | Your ability to recognize and correctly spell real English words — this is why guessing a word that "sounds right" but is misspelled still costs you points |
| Comprehension | Your ability to understand the passage well enough to know which word actually belongs in a given gap, based on meaning and grammar, not just letter-guessing |
In practice, that means two very different skills are being tested at the same time: understanding what the passage is about, and knowing precisely how to spell the specific word that fits. You can lose points on a blank even if you clearly understood the passage, simply by misspelling the word or picking the wrong grammatical form (like writing grows instead of grow after a modal verb).
How Partial Credit Works
Unlike a question that's simply marked right or wrong as a whole, each blank in a Read and Complete passage is scored on its own. A passage with seven blanks doesn't live or die on one mistake — getting five out of seven correct earns meaningfully more credit than getting zero, so there is never a good reason to leave a blank empty. An educated guess that's wrong costs you nothing you wouldn't have already lost by leaving it blank, but a correct guess adds points you'd otherwise miss entirely.
A Real Passage, Walked Through Step by Step
Here's what an actual Read and Complete passage looks like, and how to read it in the order that actually helps you:
The Domestication of Dogs
Dogs were the first animals domesticated by humans, with evidence of the relationship stretching back more than fifteen thousand years. Early wolves that t________ human presence likely s________ food scraps near ancient camps, gradually growing a_________ to living close to people. Over many g__________, humans f______ the calmer, friendlier animals, breeding them for t_____ such as loyalty and trainability rather than pure hunting ability, and this selective b_______ continued for thousands of years. This long partnership eventually produced hundreds of distinct breeds suited to herding, guarding, and companionship. Today dogs remain deeply woven into human daily life across nearly every culture on Earth.
- Read the bolded parts first. The title tells you the topic (domestication of dogs). The first sentence gives you the timeline (fifteen thousand years). The last sentence tells you where the passage ends up (dogs are now part of daily life everywhere). You now understand the whole arc of the passage without touching a single blank.
- Read the whole middle section once, ignoring the blanks. This tells you the passage is building a cause-and-effect story: wolves got used to humans → humans bred the friendliest ones → this produced today's dog breeds.
- Now fill each blank using its immediate sentence. "t________ human presence" needs a verb meaning wolves got used to people being around — tolerated. "growing a_________ to living close to people" is a set phrase — accustomed to. "breeding them for t_____" needs a plural noun describing qualities — traits.
Notice that at no point did solving this require rare vocabulary. Every answer was recoverable from context once the passage was read in the right order — title and edges first, middle second, blanks last.
Read and Complete vs. Fill in the Blanks
These two question types are frequently confused because they look similar on screen, but they test slightly different things:
| Read and Complete | Fill in the Blanks | |
|---|---|---|
| What's missing | The last few letters of a word | An entire word, chosen from a dropdown or typed freely |
| Spelling required | Yes — you complete the letters yourself | Depends on the version — sometimes selection, sometimes typing |
| Passage length | 70–110 words, one coherent short text | Usually shorter, sentence-level |
| Main skill tested | Comprehension + spelling accuracy | Vocabulary knowledge in context |
3 Mistakes That Quietly Cost Points
- Jumping straight into the blanks. Skipping the title/first-sentence/last-sentence read means you're solving each blank with less context than you actually have available.
- Typing a word that "fits" without checking it makes sense. A word can complete the visible letters and still be grammatically or semantically wrong for the sentence — always reread the full sentence with your answer inserted before moving on.
- Leaving a hard blank empty. Because scoring is per-word, an empty blank guarantees zero credit for that word. A reasonable guess based on the sentence's grammar (noun vs. verb vs. adjective) is always worth the two seconds it takes.

Frequently Asked Questions: Read and Complete (DET)
What is Read and Complete on the Duolingo English Test?
Read and Complete shows you a short passage with several words missing their final letters. You type the missing letters to complete each word correctly. It appears 3–6 times during the Comprehension section and feeds into your Literacy and Comprehension subscores.
How much time do I get per passage?
3 minutes per passage. There's no separate prep time — the timer starts as soon as the passage appears.
Are the title and first sentence always complete?
Yes. The title, the first sentence, and the last sentence of the passage are never blanked — only words in the middle sentences are turned into fill-in gaps.
Is Read and Complete adaptive?
Yes. Like several other DET question types, the difficulty of your next Read and Complete passage depends on how accurately you answered the previous one.
Should I guess if I don't know a word?
Yes. Scoring is per word, so an empty blank guarantees zero credit for that word, while an educated guess — based on the part of speech the sentence needs — has a real chance of being right and costs you nothing extra if it's wrong.
What's the difference between Read and Complete and Fill in the Blanks?
Read and Complete gives you a partial word and asks you to complete the spelling; Fill in the Blanks removes the entire word. Read and Complete more heavily tests spelling accuracy alongside comprehension.
Where can I practice Read and Complete with feedback?
