No. A cutoff score can start a speech language eligibility conversation, but it cannot end one. IDEA sets no federal cutoff, and no single measure may be the only basis for the decision. The team also weighs functional evidence, such as a language sample and what parents and teachers see every day.
Under IDEA, the team must draw on a variety of sources, including functional information about how the child communicates (34 CFR 300.304(b); 34 CFR 300.306(c)).
Recently, a school SLP asked colleagues a question many of us have faced: what cutoff do you use when your state does not set one? The replies covered a wide range of cutoffs, depending on the state or district. The most useful replies all landed in the same place. The number matters, and so does everything around it: the child's language in real conversation, what parents and teachers see, and how the difficulty affects the child at school.
Here is a practical way to build that evidence.
Does IDEA set a standard score cutoff for speech or language impairment?
No. Federal regulations define speech or language impairment as "a communication disorder, such as stuttering, impaired articulation, a language impairment, or a voice impairment, that adversely affects a child's educational performance" (34 CFR 300.8(c)(11)). The definition does not name a score.
States and districts set their own criteria, and some leave the choice to local teams. ASHA keeps an interactive map that links to each state's speech and language eligibility guidelines where they exist (ASHA, Eligibility for School Based Speech Language Services). Start there, then confirm against your state education agency and your district's current procedures.
Why isn't a cutoff score enough on its own?
Because tests and cutoffs do not line up as neatly as we would like. In a review of 43 child language tests, Spaulding, Plante and Farinella (2006) found that for more than a quarter of the tests, children with language impairment scored within 1 standard deviation of the mean on average. Few manuals reported how accurately the test identified children with and without language impairment.
The math adds a second caution. In a normal distribution, about 16 percent of scores fall more than 1 standard deviation below the mean, so a low score alone does not tell you that a child has a disability.
Two quick checks help:
- Open the manual. Look for sensitivity and specificity at the cut point you plan to use, and for the population the test was normed on. Dollaghan (2004) offers clear questions for judging diagnostic evidence.
- Ask what the score is missing. A test samples a narrow slice of language in a structured setting. It may not show how the child talks with a friend, follows a classroom routine or tells about the weekend.
What functional evidence should you add?
IDEA asks for "relevant functional, developmental, and academic information," including information from the parent (34 CFR 300.304(b)(1)), and a review of classroom observations and input from teachers and related service providers (34 CFR 300.305(a)). ASHA lists several tools that complement standardized tests (ASHA, Assessment Tools, Techniques, and Data Sources):
- A language sample from play, conversation or a story, with measures such as mean length of utterance (MLU) and number of different words.
- Parent and teacher input about how the child communicates at home and in class.
- Classroom observation during real routines.
- Dynamic assessment, where you test, teach and retest to see how the child learns.
- Curriculum based assessment using the language of the child's own classroom.
A language sample is especially useful here. When Ebert and Scott (2014) compared narrative samples with norm referenced tests in 73 school age children, the two overlapped only moderately in which children they identified, and agreement shifted with the cutpoint. The authors suggested that samples can complement tests. Use the same context and procedure as any norms you compare to, and gather enough talk. Our guide, How Long Should a Language Sample Be?, walks through the research.
What does "adversely affects educational performance" mean?
ASHA reports that U.S. Department of Education letters have consistently said educational performance is not limited to academic performance (ASHA, Eligibility for School Based Speech Language Services). A child with average grades may still struggle to join peers in play, answer questions in class or tell a teacher what happened at recess. Functional evidence is how you show that.
Speech or language impairment, or developmental delay, for a preschooler?
This came up in a second thread: what do you call it when a preschooler's scores are near average but concerns remain? IDEA allows states to use developmental delay, including delays in communication development, for children ages 3 through 9 or a subset of that range (34 CFR 300.8(b)). Each state decides whether to adopt it and for which ages, and a district may not use it if the state has not adopted it (34 CFR 300.111(b)). ASHA notes that younger children may qualify under developmental delay (ASHA, Spoken Language Disorders). Your state rules and your team guide the category.
How do you document functional evidence for eligibility?
Put the scores next to the functional evidence, so the reader sees one picture:
- the standard scores, with the test's limits for this child
- language sample measures from a reviewed transcript, with the context and length (see how to calculate MLU)
- what parents and teachers report
- how the communication difficulty affects the child at school, in and beyond academics
ASHA's guidance on school documentation notes that eligibility is decided by the IEP team, and that recommendations for eligibility are typically not part of the evaluation report itself (ASHA, Documentation in Schools). Your job in the report is to make the evidence clear.
Who decides eligibility?
The team does. A group of qualified professionals and the parent determines whether the child is a child with a disability (34 CFR 300.306(a)(1)). EASI never makes that decision. You and your team do.
Where EASI fits
EASI is language sample analysis software for English language samples. You can record live, upload audio or bring in an existing transcript. The workflow is Draft, Review, Attest, Score: EASI drafts the transcript, you review the words and speaker labels, you attest each line, and only then, when the sample supports it, EASI calculates measures such as MLU, number of different words, vocabulary diversity and the Index of Productive Syntax (IPSyn) for you to interpret. Compare tools in EASI vs SALT.
MySLP, the secure AI assistant built into EASI, answers SLPs' clinical, scientific and eligibility questions. For your state's rules, use ASHA's state map and your state education agency's current guidance. When you are ready, report drafting (in beta) can prepare a draft from your reviewed findings for you to edit and sign.
EASI is HIPAA and FERPA compliant, with a BAA and insurance.
Where can you get EASI?

FAQ
Is there a federal standard score cutoff for speech or language impairment? No. IDEA defines the category but does not set a score. States and districts set criteria, and no single measure can be the only basis for the decision.
Should I use 1.5 or 2 standard deviations below the mean? Follow your state and district criteria first. Then check the test manual's sensitivity and specificity at that cut point, and add functional evidence such as a language sample.
Can a child with average scores still qualify? The team decides, based on all the evidence and your state's criteria. Scores are one source. Functional evidence of adverse effect on educational performance, which is not limited to academics, also counts.
What counts as functional evidence for speech language eligibility? A language sample, parent and teacher input, classroom observation, dynamic assessment and curriculum based assessment. Together they show how the child communicates in daily life and at school.
Does EASI decide eligibility? No. EASI analyzes the language sample you review and attest. The clinician and the IEP team interpret the evidence and decide.
