Search for any two of these names and you will find comparison articles that line them up feature by feature: price, age range, subjects, reviews. That format is unhelpful, because these three products are not competing for the same slot in your week.
They are three different answers to three different problems:
- Outschool sells you a person. A live teacher, for a specific subject, for a fixed number of weeks.
- Khan Academy sells you feedback. Immediate, unlimited, on procedural problems, for free.
- Time4Learning sells you a structure. A sequenced curriculum with a scope and sequence, pacing and record-keeping.
If you are choosing between them, the useful question is not which is better. It is which of those three things is missing from your week.
What each actually is
Outschool: a marketplace, not a curriculum
Outschool is a platform where independent teachers sell live classes to families. Classes range from a one-off hour to a multi-week course. Pricing is per class or per week, set by the teacher, not by the platform.
Two structural facts follow from this, and both matter more than any feature comparison.
The platform does not set the curriculum. There is no Outschool scope and sequence. There is no guarantee that one class leads into another. Each teacher designs their own course, and quality varies with the teacher, not with a company standard. This is not a flaw — it is the model — but it means you are shopping for a person, and the platform mostly gives you a description and a rating to shop with.
You pay per class, which makes accumulation invisible. A weekly class at a modest per-session price looks trivial. Four of them running in parallel, across a ten-month year, is a different number. Families frequently discover the annual total in retrospect. If you use Outschool, decide up front how many concurrent classes you will run, and treat that as a budget line rather than an open decision.
What it is genuinely good at: a subject where the parent is the bottleneck. Live instruction from someone who knows the subject is not something the other two products can imitate.
What to check on a listing before paying:
- Class size. "Small group" on Outschool can mean very different numbers. Look for an explicit cap.
- Teacher's other listings and history. A teacher with a coherent set of courses in one subject is a different proposition from one with a single listing.
- Refund and cancellation terms. These are set per class and are not uniform.
- Whether it is live or recorded. Some listings are close to recorded content with a live wrapper, which changes the value considerably.
- Recording availability. For a timezone-mismatched family this decides whether the class is usable at all.
Khan Academy: a mastery engine, not a curriculum
Khan Academy is a nonprofit, free at every level, with no paid tier to upsell. That status is worth stating plainly because it changes the incentives: there is no conversion funnel, no trial expiry, no locked content.
The engine is built around mastery of procedural skills. You get a problem, you get feedback within a second, and the difficulty adapts. A skill is marked as mastered after a run of correct answers, and the system schedules review. This is a well-implemented version of an approach with strong research support: immediate feedback plus spaced retrieval.
Where it is strong: arithmetic fluency, algebraic manipulation, unit conversion, balancing equations, grammar mechanics, vocabulary — anything where the correct answer is unambiguous and the value comes from repetition.
Where it is weak: everything where the interesting part is deciding what to do rather than executing a known procedure. Writing an argument, designing an experiment, choosing which method to apply — these are judgement tasks, and a right/wrong engine cannot teach judgement. Khan has content in these areas, but the underlying system is procedural and it shows in the exercises.
It is also not a curriculum in the administrative sense. There is no grade level, no scope and sequence you can hand to an authority, no attendance record.
The most common failure: using Khan as a complete curriculum. Families do this because it is free and comprehensive-looking, and most abandon it within two months, concluding that Khan "does not work." It works. It was never designed to do that job.
Time4Learning: a curriculum with a login
Time4Learning is a subscription covering multiple subjects with a sequenced curriculum, automated grading, and reporting. The distinguishing feature is not the lesson quality — it is the structure and the paper trail.
For families in jurisdictions that require reporting, attendance records, or evidence of grade-level coverage, this is the category that solves that problem. You are not buying better explanations than Khan's. You are buying a scope and sequence, a pace, automated marking, and reports you can export.
The trade-off is rigidity. A structured curriculum assumes a child moving at roughly the expected pace through roughly the expected sequence. A child who is two years ahead in one subject and behind in another will either be bored or lost, and the platform's value — the sequence — becomes the obstacle.
Subscription pricing is monthly or annual, per student, which makes it the highest ongoing cost of the three for a single child.
Another common failure: paying for a multi-subject subscription and using one subject. If your child uses the maths and nothing else, you are paying for eight subjects you do not open. Either use more of it deliberately or buy the single subject elsewhere.
The comparison that actually matters
| Outschool | Khan Academy | Time4Learning | |
|---|---|---|---|
| What you get | Live teacher, fixed term | Practice + feedback | Sequenced curriculum |
| Pricing | Per class, teacher-set | Free | Monthly/annual subscription |
| Structure | None platform-wide | Skill-level only | Full scope and sequence |
| Records you can submit | Class completion | Progress data only | Reports, grades, attendance |
| Adapts to your pace | Yes, by choosing classes | Yes, entirely | Limited |
| Solves "parent is the bottleneck" | Yes | No | No |
| Solves "need reporting evidence" | No | No | Yes |
| Solves "needs more drill" | No | Yes | Partly |
Look at the bottom three rows. They do not overlap. No one of these three can do the job of the other two.
How to choose, in the right order
Step 1: Ask what is actually broken.
Not "what should I buy," but "what is failing." Three honest answers exist:
- My child is not getting enough repetition and I cannot mark any more problems. → Khan.
- There is a subject I cannot teach competently. → Outschool.
- I need a structure and a record because someone is checking. → Time4Learning.
If the honest answer is "I am not sure anything is broken, I just feel behind," buy nothing. That feeling is usually about confidence, not about a missing product, and no subscription fixes it.
Step 2: Check whether the problem is actually a scheduling problem.
A surprising number of "we need a curriculum" situations are really "we have no fixed time for maths." A timetable costs nothing. Try it for three weeks before spending on a platform.
Step 3: If two answers are true, use two tools, not one compromise.
A family that needs both structure and live teaching for one weak subject will do better with Time4Learning for the core plus a single Outschool class than with either alone. This is more expensive than one platform but cheaper than buying the wrong one and abandoning it. The failure mode to avoid is buying a bundle to cover a gap it does not cover.
Step 4: Set a review date before you start.
Put it in the calendar for eight weeks out. On that date, ask: what did this do last month? If the answer is vague, cancel. The single biggest waste in this category is not choosing the wrong tool; it is continuing to pay for a tool nobody opens.
A note on free trials
Khan has no trial because it is free. Outschool and Time4Learning both offer entry points that make the first month cheap. A cheap first month is a business model, not evidence of fit.
The specific trap with trial-based platforms: the trial is long enough for the novelty to carry you through it, and short enough that you have not yet hit the week where you find out whether the tool survives a bad week. Judge on week eight, not week two.
Where these fit on this site
We write about education technology because families ask us which of these are worth paying for, and the honest answer is usually narrower than the marketing. Our <a href="/editorial-policy/">Editorial Policy</a> explains how we assess tools — including the fact that we say when an assessment is based on documentation and reported experience rather than hands-on use.
If you are choosing equipment rather than software, our <a href="/blog/category/science-kits-toys/">science kit reviews</a> apply the same test to physical products, where the specifications matter more than the brand.
