(A) Specific learning disability means a disorder in one or more of the basic psychological processes involved in understanding or in using language, spoken or written, that may manifest itself in the imperfect ability to listen, think, speak, read, write, spell, or do mathematical calculations, including conditions such as perceptual disabilities, brain injury, minimal brain dysfunction, dyslexia, and developmental aphasia. Specific learning disability does not include learning problems that are primarily the result of visual, hearing, or motor disabilities; intellectual disability; emotional disturbance; or environmental, cultural, or economic disadvantage.

(B) A student with a specific learning disability is one who:

(i) has been determined through a variety of assessment tools and strategies to meet the criteria for a specific learning disability as stated in 34 CFR, §300.8(c)(10), in accordance with the provisions in 34 CFR, §§300.307-300.311;

(ii) when provided with learning experiences and instruction appropriate for the student's age or state-approved grade-level standards as indicated by performance on multiple measures such as in-class tests, grade average over time (e.g. six weeks or semester), norm- or criterion-referenced tests, and statewide assessments, does not achieve adequately for the student's age or to meet state-approved grade-level standards in one or more of the following areas:

(I) oral expression; (II) listening comprehension; (III) written expression; (IV) basic reading skill; (V) reading fluency skills; (VI) reading comprehension; (VII) mathematics calculation; or (VIII) mathematics problem solving;

(iii) meets one of the following criteria:

(I) does not make sufficient progress to meet age or state-approved grade-level standards in one or more of the areas identified in clause (ii)(I)-(VIII) of this subparagraph when using a process based on the student's response to scientific, research-based intervention; or 

(II) exhibits a pattern of strengths and weaknesses in performance, achievement, or both relative to age, state-approved grade-level standards, or intellectual development that is determined to be relevant to the identification of a specific learning disability, using appropriate assessments, consistent with 34 CFR, §300.304 and §300.305; and

(iv) does not meet the findings under clauses (ii) and (iii) of this subparagraph primarily as the result of:

(I) a visual, hearing, or motor disability; (II) an intellectual disability; (III) emotional disturbance; (IV) cultural factors; (V) environmental or economic disadvantage; or (VI) limited English proficiency.

(C) As part of the evaluation described in subparagraph (B) of this paragraph and 34 CFR, §§300.307-300.311, and in order to ensure that underachievement by a student suspected of having a specific learning disability is not due to lack of appropriate instruction in reading or mathematics, the following must be considered:

(i) data that demonstrates the student was provided appropriate instruction in reading (as described in 20 United States Code (USC), §6368(3)), and/or mathematics within general education settings delivered by qualified personnel; and

(ii) data-based documentation of repeated assessments of achievement at reasonable intervals, reflecting formal evaluation of student progress during instruction, which must be provided to the student's parents. Databased documentation of repeated assessments may include, but is not limited to, response to intervention progress monitoring results, in-class tests on grade-level curriculum, or other regularly administered assessments.Intervals are considered reasonable if consistent with the assessment requirements of a student's specific instructional program.

(D) The school district must ensure that the student is observed in the student's learning environment, including the regular classroom setting, to document the student's academic performance and behavior in the areas of difficulty. In determining whether a student has a specific learning disability, the admission, review, and dismissal (ARD) committee must decide to either use information from an observation in routine classroom instruction and monitoring of the student's performance that was conducted before the student was referred for an evaluation or have at least one of the members described in subsection (b) of this section conduct an

observation of the student's academic performance in the regular classroom after the student has been referred for an evaluation and the school district has obtained parental consent consistent with 34 CFR, §300.300(a). In the case of a student of less than school age or out of school, a member described in subsection (b) of this section must observe the student in an environment appropriate for a student of that age.

(E) The determination of whether a student suspected of having a specific learning disability is a student with a disability as defined in 34 CFR, §300.8, must be made by the student's parents and a team of qualified professionals, which must include at least one person qualified to conduct individual diagnostic examinations of children such as a licensed specialist in school psychology, an educational diagnostician, a speech-language pathologist, or a remedial reading teacher and one of the following:

(i) the student's regular teacher; (ii) if the student does not have a regular teacher, a regular classroom teacher qualified to teach a student of his or her age; or (iii) for a student of less than school age, an individual qualified by the Texas Education Agency to teach a student of his or her age.
