PI 11.36(4m)(b) (b) Upon re-evaluation, a child who met initial identification criteria and continues to demonstrate a need for special education under s. PI 11.35, including specially designed instruction, is a child with a disability under this section.
PI 11.36(5) (5) Speech or language impairment.
PI 11.36(5)(a) (a) In this subsection:
PI 11.36(5)(a)1. 1. “Home languages” mean the languages used by the child or the parent of the child in their natural environment, or the modes of communication that are used by the child or the parent of the child in their natural environment, and may include languages other than English, sign language, braille, or augmentative and alternative communication.
PI 11.36(5)(a)2. 2. “Natural environment” means settings that are natural or typical for a same-aged child without a disability and may include school, home, or community.
PI 11.36(5)(a)3. 3. “Significant discrepancy” means performance on a norm-referenced assessment that meets the cutoff score for a speech or language disorder and is significantly below age- or grade-level expectations relative to a normative sample, often reported as a percentile or standard score.
PI 11.36(5)(a)4. 4. “Speech or language impairment” means an impairment of speech or sound production, voice, fluency, or language that adversely affects educational performance or social, emotional or vocational development.
PI 11.36(5)(am) (am) Assessments and other evaluation materials used to conduct a comprehensive evaluation of a child's speech and language development shall be provided and administered in the child's home languages. Assessments and other evaluation materials shall be in the form most likely to yield accurate information unless it is not feasible to do so, and shall describe the child's speech and language abilities and how those abilities impact the child's progress in the general education environment relative to the speech and language demands of the classroom and curriculum. Interpretation of assessments shall be based on the representativeness of the normative sample and the psychometric properties of the assessment.
PI 11.36(5)(b) (b) The IEP team may identify a child as having a speech or language impairment if the child meets the definition under par. (a) and meets any of the following criteria:
PI 11.36(5)(b)1. 1. Following consideration of the child's age, culture, language background, and dialect, the child meets all of the following conditions for a speech sound disorder:
PI 11.36(5)(b)1.a. a. The child's speech sound production is documented to be delayed, as evidenced through at least one observation in a natural environment.
PI 11.36(5)(b)1.b. b. The child's speech sound production is documented to be delayed, as measured by a criterion-referenced assessment, such as a developmental scale or a phonetic inventory, or significant discrepancy in performance from typical on a norm-referenced assessment.
PI 11.36(5)(b)1.c. c. The child's intelligibility is below the expected range and not due to influences of home languages or dialect. Intelligibility ratings as documented by school staff or caregivers indicate an impact across environments.
PI 11.36(5)(b)1.d. d. Speech sound production is less than 30% stimulable for incorrect sounds.
PI 11.36(5)(b)2. 2. Following consideration of the child's age, culture, language background, or dialect, the child demonstrates the characteristics of a phonological disorder, which include both of the following:
PI 11.36(5)(b)2.a. a. The child's intelligibility is below the expected range and not due to influences of home languages or dialect. Intelligibility ratings as documented by school staff or caregivers indicate an impact across environments.
PI 11.36(5)(b)2.b. b. The child's phonological process use is documented to be non-developmental or outside of the expected developmental range, as evidenced through at least one observation in a natural environment, and by measurement of either the presence of one or more phonological processes occurring at least 40%, significant discrepancy in performance from typical on a norm-referenced assessment, or both.
PI 11.36(5)(b)3. 3. The child's voice is impaired in the absence of an acute, respiratory virus or infection and not due to temporary physical factors such as allergies, short term vocal abuse, or puberty. Following consideration of the child's age, culture, language background, or dialect, the child demonstrates characteristics of a voice impairment, which include any of the following:
PI 11.36(5)(b)3.a. a. The child's vocal volume, including loudness.
PI 11.36(5)(b)3.b. b. The child's vocal pitch, including range, inflection, or appropriateness.

PI 11.36(5)(b)3.d. d. The child's vocal resonance, including hypernasality.
PI 11.36(5)(b)4. 4. The child exhibits characteristics of a fluency disorder, following consideration of the child's age, language background, culture, and dialect. The evaluation shall include a variety of measures, including case history, observation in natural environment, norm-referenced assessment or disfluency analysis, and result in evidence of atypical fluency. The presence of one or more of the following characteristics shall indicate a fluency disorder:
PI 11.36(5)(b)4.a. a. Speech disfluencies associated with stuttering or atypical disfluency, which include repetitions of phrases, words, syllables, and sounds or dysrhythmic phonations such as prolongations of sounds or blockages of airflow typically in excess of 2% of total syllables, one second of duration, and two or more iterations in a repetition. Non-verbal physical movements, such as eye blinking or head jerking, may accompany the stuttering. Negative feelings about oral communication may be significant enough to result in avoidance behaviors in an attempt to hide or diminish stuttering.
PI 11.36(5)(b)4.b. b. A speech rate that is documented to be rapid, irregular, or both and may be accompanied by sound or syllable omissions, sequencing errors, or a high number of non-stuttering speech disfluencies such as interjections, phrase and whole word repetitions, and revisions. The resulting speech fluency pattern is considered to be significantly disruptive to efficient communication. Negative feelings and attitudes about oral communication may or may not be present under this disfluency profile.
PI 11.36(5)(b)5. 5. Following consideration of the child's age, culture, language background, or dialect, the child demonstrates a language impairment in the area of language form, content or use, as evidenced through an observation in a natural environment and by measurement of at least two of the following:

PI 11.36(5)(b)5.c. c. Developmental scales or another criterion-referenced assessment.
PI 11.36(5)(b)5.d. d. Significant discrepancy from typical language skills on a norm-referenced assessment of comprehensive language.
PI 11.36(5)(c) (c) The IEP team may not identify a child as a child with speech or language impairment when differences in speech or language are based on home languages, culture, or dialect unless the child has a speech or language impairment within the child's home languages, culture, or dialect. In determining whether the child has a speech or language impairment, the IEP team shall consider all of the following:
PI 11.36(5)(c)1. 1. The child's background knowledge, stage of language acquisition, experience with narratives, and exposure to vocabulary to discern speech or language ability from speech or language difference, such as differences due to lack of exposure, stage of language acquisition, cultural or behavioral expectations.
PI 11.36(5)(c)2. 2. Based on information and data collected, the IEP team must determine whether the child's speech or language skills are a result of a speech or language impairment or a difference due to culture, language background, or dialect.
PI 11.36(5)(d) (d) In addition to the evaluations under pars. (am) to (c), the IEP team shall evaluate a child's language by assessing the child's augmentative and alternative communication skills, when appropriate to determine the child's needs.
PI 11.36(5)(e) (e) An IEP team shall include the following:
PI 11.36(5)(e)1. 1. A speech-language pathologist licensed under ch. PI 34 who shall incorporate information from the most recent assessment to assist the IEP team in documenting whether the child meets the criteria for a speech or language impairment as well as identifying the child's speech or language needs.
PI 11.36(5)(e)2. 2. An educator with foundational knowledge in first and second language instruction and second language acquisition if the child is identified as an English Learner under 20 USC 7801 (20).
PI 11.36(5)(f) (f) Upon re-evaluation, a child who met initial identification criteria and continues to demonstrate a need for special education under s. PI 11.35, including specially designed instruction, is a child with a disability under this section.
PI 11.36(6) (6) Specific learning disability.
PI 11.36(6)(a) (a) Specific learning disability, pursuant to s. 115.76 (5) (a) 10., Stats., means a disorder in one or more of the basic psychological processes involved in understanding or using language, spoken or written, that may manifest itself in an imperfect ability to listen, think, speak, read, write, spell or perform mathematical calculations, including conditions such as perceptual disabilities, brain injury, minimal brain dysfunction, dyslexia and developmental aphasia. The term does not include learning problems that are primarily the result of visual, hearing, motor disabilities, cognitive disabilities, emotional disturbance, cultural factors, environmental, or economic disadvantage.
PI 11.36(6)(b) (b) The LEA shall promptly request parental consent to evaluate a child to determine if the child needs special education and related services if, prior to referral, the child has not made adequate progress after an appropriate period of time when provided appropriate instruction in general education settings, delivered by qualified personnel, or whenever the child is referred for an evaluation. The LEA shall meet the timeframes under s. 115.78 (3) (a), Stats., unless extended by mutual written agreement of the child's parents and IEP team.
PI 11.36(6)(c) (c) The IEP team may identify a child as having a specific learning disability if both of the following apply:
PI 11.36(6)(c)1. 1. `Inadequate classroom achievement.' Upon initial identification the child does not achieve adequately for his or her age, or meet state-approved grade-level standards in one or more of the following eight areas of potential specific learning disabilities when provided with learning experiences and instruction appropriate for the child's age: oral expression, listening comprehension, written expression, basic reading skill, reading fluency skills, reading comprehension, mathematics calculation, and mathematics problem solving. A child's achievement is inadequate when the child's score, after intensive intervention, on one or more assessments of achievement is equal to or more than 1.25 standard deviations below the mean in one or more of the eight areas of potential specific learning disabilities. Assessments used under this subdivision shall be individually administered, norm-referenced, valid, reliable, and diagnostic of impairment in the area of potential specific learning disabilities. The 1.25 standard deviation requirement under this subdivision may not be used if the IEP team determines that the child cannot attain valid and reliable standard scores for academic achievement because of the child's test behavior, the child's language proficiency, an impairment of the child that interferes with the attainment of valid and reliable scores, or the absence of individually administered, norm-referenced, standardized, valid and reliable diagnostic assessments of achievement appropriate for the child's age. If the IEP team makes such a determination, it shall document the reasons why it was not appropriate to consider standardized achievement testing, and shall document that inadequate classroom achievement exists in at least one of the eight areas of potential specific learning disabilities using other empirical evidence. The IEP team may consider scores within 1 standard error of the measurement of the 1.25 standard deviation criterion above to meet the inadequate classroom achievement criteria under this subdivision if the IEP team determines the child meets all other criteria.
PI 11.36(6)(c)2. 2. `Insufficient progress.' Upon evaluation, the child has made insufficient progress in one of the following areas:
PI 11.36(6)(c)2.a. a. Insufficient response to intensive, scientific, research-based or evidence-based intervention. The child does not make sufficient progress to meet age or state-approved grade-level standards in one or more of the eight areas of potential specific learning disabilities under subd. 1. when using a process based on the child's response to intensive scientific, research-based or evidence-based interventions. Intensive interventions may be implemented prior to referral, or as part of an evaluation, for specific learning disability. The IEP team shall consider progress monitoring data from at least two intensive, scientific, research-based or evidence-based interventions, implemented with adequate fidelity and closely aligned to individual student learning needs. The median score of three probes is required to establish a stable baseline data point for progress monitoring. IEP teams shall use weekly or more frequent progress monitoring to evaluate rate of progress during intensive, scientific, research-based or evidence-based interventions. Rate of progress during intensive intervention is insufficient when any of the following are true: the rate of progress of the referred child is the same or less than that of his or her same-age peers; the referred child's rate of progress is greater than that of his or her same-age peers but will not result in the referred child reaching the average range of his or her same-age peer's achievement for that area of potential disability in a reasonable period of time; or the referred child's rate of progress is greater than that of his or her same-age peers, but the intensity of the resources necessary to obtain this rate of progress cannot be maintained in general education. If an LEA uses insufficient response to intensive, scientific, research-based or evidence-based intervention under this subdivision paragraph for any child being evaluated for specific learning disabilities enrolled in a school, the LEA shall use insufficient response to intensive, scientific, research-based or evidence-based intervention for all such evaluations of children enrolled in that school. At least ten days in advance of beginning to use insufficient response to intensive, scientific, research-based or evidence-based intervention in a school, the LEA shall notify parents of all children enrolled in that school of the intent to use insufficient response to intensive, scientific, research-based or evidence-based intervention.
PI 11.36(6)(c)2.b. b. Significant discrepancy or insufficient progress in achievement as compared to measured ability. The method set out in this subd. 2. b. may be used only to evaluate a child attending a private school or participating in a home-based private educational program. A parent of a child attending a private school or participating in a home-based private educational program may request the IEP team to use the method set out in this subd. 2. b. Upon such request, the IEP team shall consider whether use of the method set out in this subd. 2. b. to evaluate the child is feasible. If the IEP team determines that it is not feasible to use the method set out in this subd. 2. b., the reason for that determination shall be provided to the parent in writing. The method set out in this subd. 2. b. shall not be used to evaluate a child attending a public school, including a public charter school. Upon initial evaluation the child exhibits a significant discrepancy between the child's academic achievement in any of the eight areas of potential specific learning disabilities under subd. 1. and intellectual ability as documented by the child's composite score on a multiple score instrument or the child's score on a single score instrument. The IEP team may base a determination of significant discrepancy only upon the results of individually administered, norm-referenced, valid and reliable diagnostic assessment of achievement. A significant discrepancy means a difference between standard scores for ability and achievement equal to or greater than 1.75 standard errors of the estimate below expected achievement, using a standard regression procedure that accounts for the correlation between ability and achievement measures. This regression procedure shall be used except when the IEP team determines that the child cannot attain valid and reliable standard scores for intellectual ability or achievement because of the child's test behavior, the child's language, another impairment of the child that interferes with the attainment of valid and reliable scores or the absence of valid and reliable standardized, diagnostic tests appropriate for the child's age. If the IEP team makes such a determination, it shall document the reasons why it was not appropriate to use the regression procedure and shall document that a significant discrepancy exists, including documentation of a variable pattern of achievement or ability, in at least one of the eight areas of potential specific learning disabilities under subd. 1. using other empirical evidence. If the discrepancy between the child's ability and achievement approaches but does not reach the 1.75 standard error of the estimate cut-off for this subd. 2. b., the child's performance in any of the eight areas of potential specific learning disabilities under subd. 1. is variable, and the IEP team determines that the child meets all other criteria under subd. 1., the IEP team may consider that a significant discrepancy exists.
PI 11.36 Note Note: Appendix A includes a resource for manually calculating significant discrepancy scores.
PI 11.36(6)(d)1.1. The IEP team may not identify a child as having a specific learning disability if it determines that any of the following apply:
PI 11.36(6)(d)1.a. a. The IEP team's findings under par. (c) are primarily due to environmental or economic disadvantage; cultural factors; or any of the reasons specified under s. 115.782 (3) (a), Stats., or any of the impairments under s. 115.76 (5), Stats., except s. 115.76 (5) (a) 10., Stats.
PI 11.36(6)(d)1.b. b. The IEP team's findings under par. (c) were due to a lack of appropriate instruction in the area of potential specific learning disability in par. (c) 1.
PI 11.36(6)(d)2. 2. The IEP team shall consider data demonstrating that prior to, or as a part of, an evaluation, the child was provided appropriate instruction in general education settings, delivered by qualified personnel. Appropriate instruction in reading shall include the essential components of reading instruction as defined in 20 USC 6368 (3).
