AI to learn, not to cheat
K-8 Math Practice Tests
Reimagined for the AI world
Powered by a team of AI agents designed to: Choose the perfect next question, Help you think during the practice test, Analyze your performance, and Build your personal roadmap to a higher score
Proven Results
See the story of how 8 months of focused iteration with a school math club led to extraordinary success
Steletta was built in 2024 to support a group of girls who started a math club at a top magnet school in Florida
The adaptive algorithm and question database went through 8 months of tweaks and iterations based on their feedback, to optimize for learning speed without compromising on quality
Their incredible results on the Fall 2025 FAST scores proved the model works. Now, we're opening up Steletta to students everywhere

...enhanced by AI
Dedicated AI Agents
AI running in the background throughout the test, answering questions and helping you learn right when it's most effective
Personalized Analysis
Detailed results including what to focus on to maximize score growth, foundational gaps, learning frontier, and your unique strengths
Clear Roadmap
Specific next steps and practical exercises to improve your score, skills, and continuously challenge yourself at the edge of your knowledge
A Smarter Way to Prepare for Test Day
AI helps you learn and understand concepts without cheating
- Clarifies confusing questions without giving answers
- Provides strategic hints to guide your thinking
- Explains concepts thoroughly after you submit an answer
- Unlocks in-depth reviews for every question in your test history
Discover your Learning Frontier. The fastest way to improve your score
After completing the test, you won't just get a score. The AI identifies your Zone of Proximal Development. We call it Learning Frontier and that's the precise edge of your current abilities where real learning happens
Always Challenged, Never Bored
Your personalized roadmap is built around one principle: keep you challenged, never bored. By focusing on your unique Learning Frontier, every exercise is challenging without being frustrating
The curriculum is truly uncapped. For the highest achievers, pushing the frontier means moving beyond standard K-8 material to tackle harder challenges like Math Olympiad problems
Test Prep Doesn't Have to Be Boring or Useless
Our smarter adaptive algorithm quickly identifies how to challenge you, without wasting time on endless 2+2 type of problems before moving up
Tailored tools for your specific use case
Teacher dashboard for your classroom, one click emails, in-depth report for homeschool evaluation, parent summary, and much more
Empower Your Entire Classroom
- Boost standardized test scores school-wide with AI that identifies and fills learning gaps before they impact performance
- Track every student's growth in real-time with detailed analytics that show exactly where each student stands and what they need next
- Save hours by generating professional parent reports instantly with one click
Frequently Asked Questions
Each practice test is between 17 and 21 questions. Based on the feedback of our early students, this is the optimal length to balance a delicate trade-off:
1. High Engagement: Official standardized tests are well over 40 questions, but for a practice test without the adrenaline of a real test, this is way too much, leading to boredom and loss of focus. The shorter format keeps students engaged, leading to better performance.
2. Statistical Accuracy: A test shorter than 17 questions doesn't provide enough data points to identify foundational gaps (if any) and the Learning Frontier.

Not at all. The AI is designed to help students think.
Before they submit the answer, it acts like a good teacher, asking guiding questions to help them work through the problem. After they answer, it's there to explain the concepts and show them why their answer was right or wrong. This is crucial because the moment a student is trying to solve a problem is the moment they are most motivated to learn. We leverage that peak interest to make learning more effective.
Let's put it this way: a student will never be more interested in learning what a p-value is than right after they've attempted a question about p-values and got it wrong!

No, they are guaranteed to always get different questions.
Our question bank contains over 1,000 expert-curated questions covering more than 200 unique Common Core math standards sub-topics, with at least 3 questions for each sub-topic.
Also, the algorithm knows the student's entire history, guaranteeing variety and making sure that over time they get tested on every relevant sub-topic.

While there's no single magic number, we've seen the best results when students take a practice test every 2 to 3 weeks. This provides enough time to work through the personalized study plan and make real progress on their Learning Frontier before measuring their growth.
Over time, this becomes a powerful cycle: the student takes the test → gets a personalized study plan based on their Learning Frontier → learns the most important new concepts → retakes the test → sees their score and Learning Frontier advance → repeat. As a student goes through this cycle a few times, their growth will be impressive. Even more considering the fact that the adaptive algorithm learns more about them after each test, making every subsequent plan even more effective.

The RITAI score is a modified version of the RIT score used by the MAP® test. The main difference is that RITAI also takes into account a student's interactions with the AI during the test, such as the type of questions they asked. This means that, for each answer, the model's input is not a binary right/wrong, but a more granular value that depends on the student's answer and how much support they needed.
Despite being shorter than an official standardized test, the RITAI score is quite accurate. This was tested by having our early adopter students take the test multiple times and checking the variance of the results. After 17 questions, the variance started dropping significantly, which is why we chose that as the minimum number of questions.
Furthermore, to make sure you get the full picture of a student's results, they also receive a confidence interval. This helps you understand how much of a score change is due to randomness versus actual learning.
Finally, as students take more tests, the RITAI will get more and more accurate. In statistical terms, collecting more data points lowers the variance.
