Key Points:
- A school evaluation is free, and it is your child's legal right. Under the
Individuals with Disabilities Education Act, a public school must complete an initial evaluation within 60 days of receiving your written consent. Parents routinely spend thousands on private testing without knowing this.
- Put the request in writing. A verbal mention to a teacher does nothing. A dated written request to the principal or special education director starts a legal clock and creates obligations the school must answer.
- Divorce depresses academic performance, but modestly.
Amato's meta-analysis found children of divorce scored about 0.17 standard deviations lower on academic achievement. That is real and it is small, which matters, because a large, sudden academic collapse usually means something else is going on.
- The clinical error runs in both directions. Some families pathologize ordinary grief and seek testing a child does not need. Others let "it's just the divorce" become the explanation that delays identifying a genuine learning disability for two or three years. I have seen both, and the second one does more lasting harm.
- Legal custody, not physical custody, governs educational decisions. Before you consent to anything, know what your order actually says about who holds educational decision-making authority.
A parent sits in my office and says some version of this: my daughter used to be an A student, and now she is failing algebra, her teacher says she is checked out, and I do not know whether she is struggling because of the divorce or whether something was always there and we missed it.
That is the right question, and it is a harder one than it looks. Getting it wrong in either direction costs the child. So let me give you the framework I use, then the practical mechanics, which almost no one explains to divorcing parents.
First, Untangle Three Different Things
Parents use "evaluation" to mean at least four different processes, and confusing them wastes money and time.
A school-based special education evaluation under IDEA. Conducted by the public school district, at no cost to you, to determine whether your child has a disability that requires special education and related services. If eligible, the child receives an Individualized Education Program, or IEP.
A Section 504 evaluation. A different legal pathway for children who have a disability that substantially limits a major life activity but who may not need specialized instruction. It produces accommodations rather than an IEP. Anxiety and ADHD frequently land here.
A private psychoeducational or neuropsychological evaluation. Conducted by an independent psychologist, paid for by you, often more comprehensive and considerably faster than the school process, and useful when you want depth, a second opinion, or diagnostic clarity the school is not obligated to provide.
A custody or forensic evaluation. This is an entirely different animal, ordered in the context of your legal case to inform the court about the child's best interests. It is not an educational evaluation, it does not produce school services, and it should not be conflated with one. If that is what you are actually contemplating, read
what a custody expert witness does instead.
Most families who think they need to spend four thousand dollars on private testing should begin by requesting the free school evaluation they are already entitled to. Start there.
What the Research Actually Says About Divorce and School
Paul Amato's
meta-analysis of 92 studies found that children of divorce scored lower than children in intact families across a range of outcomes, with a median effect size of about 0.14 standard deviations. His
1990s update confirmed the pattern for academic achievement specifically, with later analyses placing the academic gap at roughly 0.17 standard deviations.
Read that carefully. The effect is real, it replicates, and it is small. Divorce, on average, nudges academic performance down modestly. It does not, on average, turn an A student into a failing one.
That single fact should reorganize how you think about your child's report card. A modest dip in grades during a divorce is expected and usually self-correcting. A dramatic collapse is not typical, and treating it as the normal cost of divorce risks missing something that has a name and a treatment.
Two more findings worth having. Amato's work found the most consistent support for a family conflict explanation, meaning that much of what we attribute to "divorce" tracks more closely with the conflict surrounding it. And the research consistently identifies motivation and classroom engagement, rather than raw cognitive ability, as the pathway through which divorce affects school performance. A grieving, distracted, hypervigilant child is not less intelligent. They are spending their working memory on something other than fractions.
The Diagnostic Question, and Why It Cuts Both Ways
Divorce-related distress tends to arrive with the divorce, affects performance broadly and somewhat evenly, fluctuates with events in the case, comes packaged with emotional and behavioral signs, and improves as the household stabilizes. The child could do the work last year.
A learning disability, by contrast, is usually specific rather than global. It shows up in one domain, most often reading, writing, or math, while others remain intact. It tends to be long-standing, with a history that predates the separation if you look honestly at old report cards. It does not resolve when things calm down. And there is very often a family history, because these conditions are substantially heritable.
The most common mistake I see in divorcing families is not overreacting. It is the opposite. It is the phrase "it's just the divorce," which is comfortable, plausible, and available for years. I have evaluated children in fourth grade whose parents had been attributing a clear, unmistakable reading disability to a separation that happened in kindergarten. Those children lost three years of intervention during the developmental window when intervention works best, and they arrived at me having concluded, quietly, that they were stupid. That conclusion is the real injury, and it outlasts everything.
If a difficulty predates the separation, if it is specific rather than global, or if it does not lift as the household stabilizes, stop attributing it to the divorce and get it evaluated. You can always find out that the answer was grief. You cannot get back the years.
What You Are Actually Entitled To
This is the section nobody tells divorcing parents, and it is worth real money.
Your school has an affirmative duty to identify children. Federal law imposes a Child Find obligation: districts must identify, locate, and evaluate children who may have a disability requiring special education. This duty exists whether or not you ask.
You can request an evaluation, in writing, at any time. You do not need a teacher's referral, a diagnosis, or anyone's permission. Send a dated written request to the principal or the district's director of special education, stating that you are requesting a comprehensive evaluation under IDEA to determine eligibility for special education services. Keep a copy. Email creates a timestamp; certified mail creates proof.
The clock then starts. Under
IDEA, the initial evaluation must be completed within 60 days of the school receiving your informed written consent, unless your state sets a different timeframe. Many states do, so check yours.
The school cannot simply ignore you. If the district declines to evaluate, it must provide prior written notice explaining why, what information it relied on, and what your options are. A teacher saying "let's give it more time" is not a legal response to a written request.
It costs you nothing. The evaluation is free.
If you disagree with the school's evaluation, you can request an independent educational evaluation at public expense. The district must then either fund it or file for a due process hearing to defend its own work. This right is genuinely powerful and genuinely underused.
Those are your rights. Use them.
The Divorce Problem: Who Gets to Consent?
Here is where educational evaluation collides with your custody order, and where I watch families get stuck.
Educational decision-making is governed by
legal custody, not physical custody. Where your child sleeps is a separate question from who is authorized to make decisions about their schooling. Many parents do not know this, and some discover it only when a school refuses to proceed.
If you hold sole legal custody with respect to education, you can generally consent on your own. If you share joint legal custody, you may need your co-parent's agreement, and schools facing a disputed consent will frequently decline to act until the parents agree or a court resolves it. Some orders assign educational decision-making to one parent specifically. Read yours before you do anything else, and if it is ambiguous, ask your attorney rather than guessing.
If your co-parent refuses, work in this order. Ask first, in writing, and make it about the child rather than about the case. Attach the teacher's observations and the report card so the request rests on evidence rather than on your say-so. If that fails, mediation is often faster and far cheaper than motion practice. If it still fails, this is exactly the kind of specific, child-focused, documented request that courts tend to grant, and it presents well because it is manifestly reasonable.
A Warning
Do not weaponize your child's evaluation.
I have watched a parent request testing primarily to build a record that the other parent's home was harming the child academically. I have watched a parent refuse a plainly necessary evaluation because the other parent proposed it. Both parents believed they were advocating for their child. Neither was.
An evaluator will see it. The school will see it. And your child, who is not stupid, will absolutely see it. The purpose of an educational evaluation is to help a child learn to read. It is not a piece of custody evidence, and treating it as one is both transparent and disqualifying.
If you are unsure whether your motive is clean, ask yourself a single question: would I still want this evaluation if it produced findings that were inconvenient for my case? If the honest answer is no, stop, and talk to someone before you proceed.
What Effective Co-Parenting Looks Like Here
Given that conflict tracks so closely with children's outcomes, and given the
American Academy of Child and Adolescent Psychiatry's emphasis on routine, reassurance, and steadiness, a few specifics.
Both parents should be on the school's contact list, receive the same communications, and attend the same meetings. Schools should not be routing information through one parent and hoping it travels. Ask the school to send everything to both of you, and put that request in writing.
Both of you should attend the IEP or 504 meeting if you possibly can. It is one hour, it is about your child, and sitting in the same room without incident is a gift to a child who is watching very carefully to see whether their difficulty is going to become another thing you fight about.
Homework routines should be as consistent as you can make them across two households. Same expectations, same bedtime, same place, same time. Predictability is a cognitive resource, not just a comfort.
And tell your child what an evaluation is, in plain terms, before it happens: "We are going to have someone figure out how your brain learns best, so school stops feeling so hard. It is not a punishment and there is nothing wrong with you." Children who are not told invent an explanation, and the explanation they invent is almost always that they are the problem.

Frequently Asked Questions
Does my child need an educational evaluation because of our divorce? Probably not on the basis of the divorce alone. Divorce depresses academic performance modestly, on the order of 0.17 standard deviations in the research, and a mild dip that improves as the household stabilizes is expected. Seek an evaluation if the difficulty is specific rather than global, if it predates the separation, or if it does not improve over time.
Do I have to pay for an educational evaluation? No. Public schools must evaluate children who may have a disability at no cost to the family, and federal law requires the initial evaluation to be completed within 60 days of your written consent. Many parents pay thousands for private testing without ever learning they were entitled to a free school evaluation first. Private evaluations still have real value, particularly for speed and depth, but start with what you are already owed.
Do I need my ex's permission to get my child evaluated? It depends on your order. Educational decisions are governed by legal custody rather than physical custody. If you share joint legal custody, you likely need agreement, and schools will often decline to proceed with a disputed consent until the parents agree or a court resolves it. Read your order, and ask your attorney if the language is ambiguous.
What if my co-parent refuses the evaluation? Ask in writing, framed around the child and supported by the teacher's observations and report card rather than your opinion. If that fails, try mediation, which is faster and cheaper than court. If it still fails, a specific, documented, child-focused request is exactly the kind of relief courts tend to grant.
How can I tell if it is the divorce or a learning disability? Divorce-related difficulty typically arrives with the divorce, affects performance broadly, comes with emotional and behavioral changes, and improves as things stabilize. A learning disability tends to be specific to one academic domain, long-standing, present in the history if you look at old report cards, often familial, and it does not resolve when the household calms down. When in doubt, evaluate. The costlier error by far is attributing a real disability to the divorce for years.
