Education Code section 52164.1
(a)
A determination of the primary language of each pupil enrolled in the school district. The primary language of new pupils shall be determined as they enroll. Once determined, the primary language need not be redetermined unless the parent or guardian claims there is an error. Home language determinations are required only once, unless the results are disputed by a parent or guardian.(b)
An assessment of the language skills of all pupils whose primary language is other than English. All the skills listed in subdivision (m) of Section 52163 shall be assessed, except that reading and writing skills need not be assessed for pupils in kindergarten and grades 1 and 2. For those pupils who, on the basis of oral language proficiency alone, are clearly limited English proficient, assessment of reading and writing skills shall be necessary only to the extent required by subdivision (c). This assessment, which shall be made as pupils enroll in the district, shall determine whether such pupils are fluent in English or are of limited English proficiency.(c)
For those pupils identified as being of limited English proficiency, a further assessment shall be made to determine the pupil’s primary language proficiency, including speaking, comprehension, reading, and writing, to the extent assessment instruments are available. Parallel forms of the instruments used to determine English proficiency shall be used, if available. The results of the parallel assessment shall determine the extent and sequence in which English and the primary language will be used in the instruction of basic skills.
