Schools do not have to wait for a child to fail before considering a special education evaluation. Under IDEA’s Child Find requirements, public schools must identify, locate, and evaluate children who are suspected of having a disability and needing special education services—including students who are still advancing from grade to grade.
When should speech or language concerns trigger a closer look?
A referral for evaluation may be appropriate when there is a reasonable suspicion that a communication disability could be affecting the student’s educational functioning. The concern may come from a parent, teacher, SLP, physician, intervention team, or another person involved in the child’s education or care.
Speech sound concerns
Reduced intelligibility, persistent sound errors, or difficulty being understood that affects participation or communication.
Language concerns
Difficulty understanding directions, vocabulary, grammar, questions, narratives, or expressing ideas.
Fluency / voice concerns
Stuttering, voice differences, or communication avoidance that may affect classroom participation.
Functional communication concerns
Difficulty communicating needs, using AAC, interacting with peers, or accessing classroom routines.
One isolated difficulty does not automatically mean a disability is present. The key is whether the available information creates a reasonable suspicion that the student may have a disability and may need special education services.
Child Find applies even when a student is passing
IDEA specifically includes children who are suspected of having a disability and needing special education even though they are advancing from grade to grade. Passing grades, good behavior, or strong effort do not eliminate Child Find responsibilities when other data suggest a disability may be present.
Can a school require months of intervention first?
Schools may use MTSS, RTI, speech sound supports, classroom strategies, or other interventions to help students and collect useful data. Those supports can continue during the evaluation process. But intervention cannot be used to delay or deny an evaluation when the student is suspected of having a disability and needing special education.
Texas evaluation timelines: the 15–45–30 framework
Families often hear the shorthand 15–45–30. It is useful, but each number starts from a different event and there are important exceptions.
| Timeline | What it generally means in Texas |
|---|---|
| 15 school days | After the district receives a written parental request for an initial special education evaluation from the appropriate district administrator, the school must provide prior written notice of its proposal to evaluate or refusal to evaluate, along with required procedural information. If it proposes to evaluate, it must give the parent an opportunity to provide written consent. |
| 45 school days | After the district receives written parental consent for the full and individual initial evaluation, the evaluation and written report generally must be completed within 45 school days, subject to Texas absence and end-of-year exceptions. |
| 30 calendar days | After the written initial evaluation report is completed, the ARD committee generally must make the initial eligibility determination—and, if appropriate, develop the IEP and placement—within 30 calendar days, subject to summer exceptions. |
Texas has detailed rules for student absences and evaluations that begin close to the end of the school year. For an exact deadline in a specific case, families and schools should use the current TEA FIIE timeline rather than counting from a simplified chart.
Does the request have to be in writing?
A parent may request a special education evaluation verbally or in writing. Texas guidance explains that a verbal request still requires the district to follow federal Child Find and prior written notice requirements. However, the specific Texas 15-school-day response timeline is tied to a written parental request received by the district’s special education director or another district administrative employee.
What happens after the school receives a request?
The school does not have to agree with every request, but it should respond. If it proposes an evaluation, it provides prior written notice and seeks informed parental consent. If it refuses, it must provide prior written notice explaining the refusal and the information used as the basis for that decision.
Once consent is obtained, the evaluation should be sufficiently comprehensive to identify all of the child’s special education and related service needs—not only the area that first triggered the referral.
Questions to ask when you are unsure whether to request an evaluation
- Has this concern persisted despite reasonable instruction or support?
- Does it affect the student in more than one class, activity, or setting?
- Is the student working significantly harder than peers to communicate or understand?
- Are teachers, parents, or other professionals seeing similar concerns?
- Could the difficulty reflect a disability rather than simply a skill that needs more practice?
- Is there enough concern that the school should gather formal evaluation data rather than continuing to wait?
The bottom line
Intervention and evaluation are not competing choices. Schools can support a student while also evaluating when a disability is suspected. In Texas, parents can request an evaluation, and a written request helps activate clear state timelines. The purpose of the evaluation is to replace guesswork with data.
