The Study Everyone Quotes, and What It Left Out
You will see a figure repeated everywhere: 34 hours of Duolingo equals a semester of college Spanish. It is worth knowing where that came from before you plan around it, because the study behind it was run on adults and is older than most of the kids it now gets quoted at. It comes from research conducted in late 2012 by academics at Queens College and the University of South Carolina, commissioned by Duolingo, which estimated that a beginner needed somewhere between 26 and 49 hours to cover first-semester material.
Three things sit underneath that number and rarely travel with it. Every participant was an adult of 18 or over, so it tells you nothing directly about a nine-year-old. The study had no proper control group. And it is fourteen years old, which in software terms means it measured an app that no longer exists. Applied linguists have published critiques of how the finding gets reported, and those critiques are worth knowing about before you build a plan around the number.
What Your Child Gets From the App
Vocabulary, mostly, and a feel for how Spanish sentences go together. Your child will build a large store of words they recognize on sight, absorb the shape of common constructions, and get a daily habit that survives the weeks when nothing else does. For a subject many homeschool families keep meaning to start, a habit that costs nothing is not a small thing.
What your child gets less of is comprehension at speed and the ability to produce Spanish under pressure. Tapping the right tile is recognition. Speaking to a person who is waiting for an answer is something else, and the app does not rehearse it. This is the ordinary shape of app learning rather than a scandal, and it matters here because the fix is unusually available in Spanish.
Fitting a second language into the week is easier when the rest of the year already has a shape.

The Advantage American Families Waste
Here is the part that separates Spanish from every other language your child might pick. Spanish-language television and radio broadcast across most of the country. Public libraries carry Spanish picture books, chapter books and novels, and interlibrary loan reaches far more. Most metro areas have Spanish-speaking communities, shops, churches and neighbors. A family learning Japanese or German has to manufacture all of this. You have it already.
Almost nobody uses it. Families run the app, feel vaguely guilty about the streak, and never once put Spanish television on during lunch. That is the single change that moves a child furthest, and it costs nothing and requires no scheduling. Put Spanish in the room your child is already in.
Why Hearing It Matters More Than Drilling It
The linguist Stephen Krashen argued that people pick up a language mainly by understanding messages a little beyond their current level, an idea usually called comprehensible input. It is an influential hypothesis rather than a closed question, and you do not have to accept all of it to notice what follows from it. Hours of Spanish your child can mostly follow will do more than the same hours spent on isolated words.
The practical version: find Spanish your child can follow about eighty percent of, and let them swim in it. Cartoons made for Spanish-speaking children work because the visuals carry the meaning. Free video channels built for learners work because they are paced for it. Songs work, especially with young kids. The bar is understanding most of it, not all of it, and a child who understands most of it is learning even when it feels like watching television.
Getting Your Child Speaking
Input builds understanding, and speaking still has to be practiced separately. The cheapest version is your child narrating their own day out loud, badly, for two minutes. After that, a conversation partner beats everything: a tutor twice a month, a neighbor, a community group, a Spanish-speaking family at church. Twenty minutes with a person who will not switch to English does more than a week of tapping.
Expect discomfort, and expect your child to tell you they hate it. Producing a language is harder than recognizing it, which is exactly why it is the part that builds the skill. Keep the sessions short and frequent rather than long and rare, and let them be bad at it out loud. One rule helps more than any curriculum here: whoever your child speaks with should not rescue them into English at the first pause. Most relatives will, kindly and instantly, and it undoes the whole point of the exercise.
How to Run Spanish in a Homeschool Week
Ten to fifteen minutes of app on most days, some Spanish playing in the background of ordinary life, and one genuine speaking slot a week or a fortnight. That is the whole program, it costs close to nothing, and it beats most paid Spanish curricula for a family that will stick with it. Start listening young, add the app when your child reads comfortably, and add speaking whenever you can arrange it.
If you are teaching a high schooler and thinking about the transcript, that is a separate question with its own rules, and app hours are not the currency it deals in. The same shape of answer applies to any free platform: whether Khan Academy is enough for homeschool math works through it on the math side, and the French version of this question covers what changes when the free input is not lying around.

A Note from Homeschool Teacher Guide: What This Really Means for You
We think the app question is the wrong one to spend your energy on. Duolingo is fine, it is free, and if your child enjoys it you should keep it. The reason so many homeschooled kids end up with four years of Spanish and no Spanish is not that they picked the wrong app. It is that the app was the entire plan.
What we would rather you take away is the advantage sitting in your house. You live in a country where Spanish is on the radio, in the library, and three doors down, and no other language your child might learn comes with that. Use it badly, use it inconsistently, use it while making dinner. A child who has heard hundreds of hours of Spanish they mostly understood is in a different position from one with a very long streak, and getting there does not require you to buy anything.

How Many Hours Equal a Semester?
A 2012 study commissioned by Duolingo put it between 26 and 49 hours, averaging about 34, to cover first-semester college material. Hold three caveats alongside it: the participants were adults, there was no proper control group, and the study is fourteen years old, so the app it tested is not the one your child will open.
Do We Still Need a Curriculum?
Often not. The app carries vocabulary and sentence patterns for nothing, and what it leaves out is hours of understandable Spanish and real speaking practice. Both of those are cheaper to add than a second program is to buy, which is unusual and is a function of how much Spanish is around you.
What Is Comprehensible Input?
It is the idea, associated with the linguist Stephen Krashen, that people acquire a language mainly by understanding messages slightly beyond their level. It is an influential hypothesis rather than a settled matter. It bears on Spanish because understandable Spanish is easy for an American family to find and free.
Where Do We Find Free Spanish?
Spanish-language television and radio reach most of the country, libraries carry Spanish books for every age, and free video channels exist that are paced for learners. Many communities have Spanish-speaking neighbors, shops, churches and groups. Most families have all of this within reach and use none of it.
What Age Should We Start?
Listening can start at any age and there is no deadline to miss. Songs, shows and picture books suit young kids long before an app makes sense. The app fits a child who reads comfortably and will sit for ten minutes, which lands around eight or nine for most.
