Dearest reader,
Every so often, a breadcrumb lands on my desk that makes me put down the tea, straighten the pearls, and start reading.
This was one of them.
It is called the MiGreatDataLake.
And if you are a Michigan parent or taxpayer who has never heard of it, you are probably not alone.
Michigan provided approximately $13.5 million in public funding to build this statewide education data infrastructure. Copper Country ISD serves as the fiscal agent, while the Michigan Association of Intermediate School Administrators, MAISA manages the project.
And this is no longer simply a proposal sitting in a feasibility study.
According to MAISA's own 2025–26 annual report, more than 140 pilot districts representing more than 240,000 students have participated.
More importantly, the report states:
"Student demographic and assessment data is flowing from the Michigan DataHub to the MiGreatDataLake."
So naturally, I kept reading.
The project involves Amazon Web Services, Cloudwick/Amorphic and Pariveda. Its architecture is being developed to bring together education data that traditionally lives in separate systems.
And the vision extends considerably beyond demographic information and assessment scores.
Project documents describe an architecture capable of incorporating structured Student Information System data as well as unstructured information, including student artifacts and teacher observations.
An earlier feasibility study discusses the potential value of combining information such as student records, academic performance, formative assessments, behavioral indicators, social-emotional surveys, attendance and extracurricular activities.
Important distinction:
I have NOT found evidence that all of those categories are currently being placed into MiGreatDataLake.
What I can document as currently flowing is demographic and assessment data.
Receipts aren't very useful if we only keep the convenient ones.
And then there is artificial intelligence.
The project's feasibility study included an estimated $2.7 million "Artificial Intelligence Layer," describing advanced models capable of analyzing large datasets, identifying patterns and producing predictive insights.
Other project materials discuss AI/ML, predictive analytics and natural-language querying.
But here again, the distinction matters.
I have NOT found evidence establishing that an AI model is currently processing individual Michigan students' records.
The data lake is operational.
Student data is flowing.
AI and predictive analytics are part of the planned architecture.
Those are three separate facts, and I am not going to turn them into one sensational sentence simply because it would make a better headline.
Now let's talk privacy.
MiDataHub, which already serves hundreds of Michigan districts, has existing data-hosting agreements, encryption, authentication, security monitoring and FERPA-related protections.
MiGreatDataLake's own documents also repeatedly discuss FERPA, security and data governance.
So no, I am not telling you Michigan dumped children's records onto an unsecured Amazon server.
That isn't what the receipts say.
What the receipts DO say is that Michigan is building something substantially larger.
Project materials describe a future P-26 Data Trust, additional datasets, predictive analytics, artificial intelligence and an education-data continuum extending beyond the traditional K–12 years.
The current annual report even discusses eventually evaluating additional "P-26 data sets for data lake ingestion."
And that leaves me with some very simple questions.
How many Michigan parents know this exists?
What information about their children is currently in it?
As additional datasets are considered, what information will be added?
Who gets access?
How long is information retained?
What role will artificial intelligence eventually play?
And as the system grows, who ultimately controls the lake?
Those aren't accusations.
They're questions.
And when more than $13.5 million in public money has been spent building a statewide infrastructure through which data representing more than 240,000 Michigan students is already moving, I don't think parents should need a technology degree, a government grant report and several hours down a rabbit hole just to know it exists.
Perhaps the most important question is the simplest one:
Did you know about MiGreatDataLake?
Because until this breadcrumb arrived in my inbox, I didn't.
With receipts and respect,
Lady Budgetdown
