Paying with ESA, Scholarship, or Charter Funds
Can I use ESA, scholarship, or charter funds for this kit?Yes. Families across the country buy Timberdoodle kits with state scholarships, education savings accounts (ESAs), and charter school funds—and most families who buy a full year of curriculum from us pay nothing out of pocket. See which programs we work with and how to order with yours.
Do I order here, or through my program's marketplace?
That depends on your program. Some let you shop right here on timberdoodle.com and check out with your program's payment method. Others handle ordering inside their own marketplace, where you search for Timberdoodle and place the order there. The guide above walks through each one. If you're not sure which yours is, email us at mail@timberdoodle.com and we'll tell you.
Will I be charged anything myself?
No. When your program orders directly, your program is billed—not you. If you see a balance-due line on a program order, that's the amount your program pays, not something you owe.
My award won't cover a whole kit. What then?
Kits come in three levels—Basic, Complete, and Elite—so there's usually a version that fits your award. Many programs also allow customizing a kit, which lets you swap or drop items before you order. Individual items work too, if you'd rather fill the gaps in what you already own.
Which edition can I use—Classic or Nonreligious?
Your program's rules decide. Most funding programs require non-religious materials, and that's exactly what the Nonreligious edition is: the same kit, built without faith-based materials. Classic is there for families whose program allows it, or who are buying with their own funds.

Each Kit Tier includes specific subjects and courses, starting from the minimum required. Check out the comparisons below to see which Kit Tier is right for you.

Find answers to the most frequently asked questions about this product below:
We asked the families who used our 12th grade kit how long their students spent on "school." Most of the families worked on academics 4 or 5 days a week and spent 3-5 hours a day specifically on Timberdoodle materials. It is common for families to spend more or less time than that, so don't stress if your schedule doesn't exactly match up. And, of course, the time you spend will be greatly impacted by how in-depth your student takes their studies, their learning approach, how distractible they allow themselves to be, and much more.
Feeling a little queasy about giving grades? Don't worry—you've totally got this. Grading high school at home might sound scary, but it's really just another skill you'll master, like teaching long division or surviving a field trip to the science museum. Check out this article for tips and suggestions.
Not sure if it’s time to move up? Totally normal!
A great place to start is with our Placement Tests. We have complete tests for younger kiddos to show exactly where they are. For older students, you’ll want to focus on the math and language arts sections to get a good feel for their readiness.
Kids are usually ready to jump into the next kit—with maybe a few exceptions. If your child is heading into 3rd grade but places into 2nd-grade math, no problem! You might want to grab the 3rd-grade kit and simply swap out the math.
If a subject didn’t stick last year, now’s your chance to figure out why.
- Maybe your child just missed a few concepts (hello, summer review!).
- Maybe the curriculum didn’t click.
- Maybe math just isn’t his jam (yet).
- Or maybe he needs a little extra support—and that’s okay!
One of the best things about homeschooling? You’re not locked into a one-size-fits-all timeline. You can customize learning to fit your child and help them succeed at their own pace.
Ready to start exploring? We’re here to help every step of the way!
Nope—and that's totally normal!
Here's the deal: Accreditation is for schools, not curriculum. Your local school district might be accredited, but their textbooks aren't. Accreditation looks at things like teacher degrees and classroom hours, not the books or materials being used. And since Timberdoodle kits aren't a school—they're a collection of awesome learning tools—there's nothing to accredit.
If you see a homeschool program claiming to be "accredited," just remember: it's the school that's accredited, not the curriculum.
And don't worry—no state requires homeschool curriculum to be accredited. (Phew!)
What you really want to know is: "Will Timberdoodle meet my state's homeschool requirements?" In most cases, the answer is yes—we meet or beat what's needed! However, every state's rules are a little different, so we recommend checking yours. (We even have a quick cheat sheet to help!)
Still scratching your head? Reach out—we'd love to help you figure it out!

We've also been recognized for our Boxed Curriculum and even for being Most Unique. These awards are a testament to how much our customers love our kits!

Started during the pandemic and wrapping 4+ years of world schooling
Vivienne M.
Our 12th grader was shot into online high school during the pandemic, which was a huge shock to the whole family and with that change we decided to go full world schooling, which has been a blessing. The online curriculum schedule guide, which is customizable has been a great way to keep all of us on track. We never thought we’d go this route, but with a customizable curriculum we have been able to help our two sons move through their education, while experiencing the world.

Twelfth-Grade Curriculum Kit
Manda S.
Wow, I love this curriculum. This is the first year we've pulled our teen out of the public school system and I am so happy we did. He's blossoming before our eyes with this engaging curriculum. I finally she him taking responsibility for his education.

Flexible to Schedule
Michelle G.
I appreciate that each year every Timberdoodle Curriculum Kit gets thorough consideration for updates and changes. We are very excited to order and use this year's complete 12th grade kit, especially with the inclusion of the Notgrass Company's Exploring World History curriculum. From experience, every Notgrass resource we've used has been incredibly easy to schedule and use but rich and rewarding to study. We travel for speech and debate tournaments and have to adapt our schedule depending on the season and how much travel is involved. The way Timberdoodle kits are set up is so flexible, it takes the work out of juggling our time. And I know Notgrass history resources flow right in with that philosophy.
