For SAT-prep academies & schools
The whole SAT program, measured and run in one place.
Diagnostics, mock tests, homework, parent reports, and a question bank of 6,000+ tagged items. Every mock is scored by an ability model, and every result becomes a diagnosis and a plan. Delivered under your academy's own name.

Under every tool, one measurement brain.
Seneca keeps an honest read on where each student actually stands, then puts it a question away. Ask in plain language and it answers from your own roster, not the internet.
It finds the cause, not the symptom.
Most tools count what a student got wrong and hand back the same topics. Seneca separates the skill that is actually failing from the one that only looks like it, and names the cause the score depends on.
A second teacher who has read every student.
Ask Seneca in plain language and it answers from your own roster: who is about to stall, what to cover tomorrow, which set to assign to whom. It drafts, you decide.
Five tools. One measurement spine.
Most academies stitch a program together from six apps that never talk to each other. Here, every tool reads from the same measure of each student, so a mock score, a homework set, and a parent report all mean the same thing.
Rasch-equated mock tests
A flat-curve mock can't tell a lucky day from real growth. Every Vindica mock is scored with an ability model, so a 1380 means the same thing on every form and a gain is a gain. Most platforms won't tell you how they score. This is how.
Run it live, review it together
Students join with a code on their own device, in the room or on a Zoom or phone call. No screen-share: you drive, and every screen follows, with answers landing as they commit. Run live practice from a set you build, or pull up a finished mock or assignment and review it with the class question by question, with Seneca's note on every answer and its traps.
Homework from the miss-pattern
No generic worksheets. Seneca drafts each student's next set against the skills their data shows lowest, each with a mastery estimate and a confidence level. Approve in a tap, or let it run.
Parent reports that cite the number
Every sentence traces to a number the student produced. Drafted from the data, held for your review, sent in your name.
1380, up 60 this month. On pace for her 1500 goal by the fall test.
Vocabulary in context, 40 to 58 mastery after three targeted sets, her single biggest drag on reading.
The rest of her misses are pace, not skill. She answers correctly given time, but runs 78s a question against a 70s target and leaves points on unfinished ones.
Timed reading modules. Recheck at Mock 7.
6,000+ questions, vetted and loaded
Not a scrape, not an AI dump. Original, Bluebook-faithful items put through a multi-stage review, tagged by skill, ready to assign on day one. Bring your own on top, and see per-question analytics on what your students really miss.
Not a chatbot. A measurement loop.
A chatbot answers whatever a student asks and forgets them by the next question. Seneca does the opposite: it measures where each student actually is, prescribes the one thing to fix next, and checks at the following mock whether it moved. Then it goes again.
Find the real weak spot
Every diagnostic and mock produces one ability estimate per domain, so you work on the real bottleneck instead of guessing at it.
Prescribe the fix
The teacher assigns targeted practice and live review aimed at exactly that domain, and the platform tracks it through to completion.
Prove it moved
The next mock re-estimates that same domain, so you see whether the score actually moved. Then the loop starts over.
Why not just use ChatGPT?
For explanations, use it. ChatGPT is a good tutor's mouth. What it cannot be is the memory, the measurement, and the accountability a program runs on.
In their words.
Directors, instructors, and students at SAT academies and tutoring studios across Korea. Names changed, words theirs.
"Report night used to be four hours of copy-paste. Now the per-student numbers are already written up, so I spend that time reading what actually changed instead of assembling it. It flagged two kids who had quietly stalled before I would have noticed."
"New instructors used to need a full term to calibrate. Now they read the same ability estimate I do, so a 1400 means the same thing across the whole room."
"I could watch my reading score actually move between mocks instead of bouncing around at random. Seeing it hold at the higher number is what kept me going."
"It stopped handing me random sets. Every week it is the exact thing I keep missing, so practice finally feels like it is going somewhere."
Questions academies ask.
No. You import your students and run your first mock the same afternoon. No setup fee, and no annual contract.
No. $30 per active student covers unlimited mocks, practice, homework, and reports. Your bill does not change because a student took another test.
Those host tests. VindicaOS scores them with an ability model and tells you the one domain to work on next for each student, then checks at the next mock whether it moved.
Yes. Your name, your color, your domain, at no extra cost. Students and parents see your academy, not us.
High, and we are particular about it. Every item is original, written to real Bluebook difficulty and format, and put through a multi-stage authoring and review process before it ever reaches a student. That is closer to how a testing organization builds items than to a scrape or an AI dump. Each one arrives tagged by skill, and you can layer your own questions on top.
Yes. The same platform, no cost, after a light eligibility check.
Yes. Each academy's data is isolated at the database level, encrypted in transit and at rest, and never sold. You own it and can export or delete it at any time, and we'll sign a Data Processing Agreement. See how we handle data.
