California’s new TK multilingual screeners mark a shift in how the state plans to support young children whose primary language is not English. Rather than using a tool designed for older students, the state has identified age-appropriate screening instruments for transitional kindergarten children who may benefit from added English language development support.

As of October 18, 2026, the policy is still in a preparation phase. The California Department of Education named two approved instruments on March 27, 2026: IPT Early Childhood and preLAS, both available in English and Spanish, according to the CDE screening instruments letter. A voluntary field test is scheduled for the 2027-28 school year, and mandatory statewide screening is scheduled to begin in the 2028-29 school year.

What TK Multilingual Screeners Are Designed To Do

The purpose of TK multilingual screeners is narrower than many families may assume. The screeners are intended to help determine whether a TK child whose Home Language Survey indicates a primary language other than English may benefit from additional English language development support. They are not described as a full language evaluation, a disability assessment, or a measure of a child’s total bilingual ability.

TK Multilingual Screeners And Family Input

TK multilingual screeners begin after the Home Language Survey indicates that a child’s primary language is other than English. That makes family information a key part of the process. Families are often the best source of information about which language or languages a child hears, understands, and uses across home routines, siblings, caregivers, community settings, and media.

For bilingual development, this matters because a four- or five-year-old may not show the same skills in each language at the same time. A child might explain feelings more easily in the home language, use school words in English after entering TK, or mix languages during play. Those patterns can be typical in bilingual development, but they still need careful interpretation by educators who understand the child’s exposure and opportunities to use each language.

What The Screeners Should Not Be Used For

California’s rules place clear limits on how results may be used. The CDE letter states that TK multilingual learner screening results cannot be used to identify a pupil as an English learner under Education Code Section 306, and they also cannot be used for teacher evaluations, accountability, reclassification, gifted and talented education, special education identification, or grade promotion and retention.

That limitation is helpful from a child-development perspective. Screening can point to the need for closer support, but it should not become a high-pressure label. A screener gives limited information at one point in time. It should be read alongside family input, classroom observation, opportunities to use both languages, and the child’s comfort with the adult, setting, and task.

Why Age-Appropriate Screening Matters In TK

Transitional kindergarten serves young children, and many are still developing attention, turn-taking, vocabulary, narrative skills, and confidence in group settings. A tool that is acceptable for older children may not fit the developmental profile of a four-year-old. The state’s move toward age-appropriate instruments reflects that concern.

Why The ELPAC Change Matters

The Legislative Analyst’s Office reported that, as of the 2024-25 school year, TK students were exempt from taking the English Language Proficiency Assessments for California because of concerns that the ELPAC was developmentally inappropriate for younger TK students. The same report described a 2024-25 state budget allocation of $10 million to support a multilingual learner screener in TK, including funding for the CDE to contract for the tool and training at no cost to districts; see the LAO budget analysis.

For families, the key point is not simply that one test was replaced by another. The deeper issue is fit. Young children communicate through gestures, short phrases, play, drawing, storytelling, peer interaction, and routines. Any screening process for this age group needs to account for attention span, developmental variation, and language exposure.

What Teachers May Notice Beyond Scores

Classroom staff can learn a great deal by watching how a child communicates during ordinary activities. Does the child use words, gestures, pointing, facial expressions, or imitation to participate? Does the child understand routines after watching peers? Does the child attempt to communicate with adults, with other children, or both? These observations cannot replace a required screener, but they can help adults avoid reducing a child’s language profile to a single score.

This is especially relevant for children who are new to English. Quiet behavior in the classroom does not automatically mean a child lacks language. Some children observe before speaking. Others may speak freely at home but say very little at school until they feel secure. Teachers need time, context, and family partnership to understand what a child can do across languages.

How Families Can Support Early Language Development

Families do not need to wait for statewide implementation to support communication. Everyday interaction remains one of the most useful ways to build language: shared book reading, pretend play, songs, storytelling, cooking routines, neighborhood walks, and conversations during caregiving all give children reasons to listen and respond.

Home language use is not a barrier to learning English. Within the limits of the research provided here, California’s screening policy is focused on identifying whether added English language development support would be beneficial; it does not say families should reduce the home language. Children benefit when adults understand what they can express across their full language experience, not only what they can say in English during a brief school task.

• Share language history with the school. Tell teachers which language the child hears most, which language the child uses with different people, and whether the child has had prior group-care or preschool experience.
• Keep using meaningful home routines. Talking during meals, play, errands, and bedtime gives children repeated chances to hear and use language in context.
• Ask how results will be interpreted. Families can ask whether screening information will be combined with classroom observation and family input.
• Watch growth over time. A child’s language may look different after several weeks in TK than it did during the first days of enrollment.

Families looking for home-based ideas can also review bilingual development resources that focus on reading routines, home language support, and realistic progress checks. Creative activities can help children communicate as well; related family learning ideas can be found through The Sketchbook Project, which offers engaging ways for families to explore language and creativity together.

What Educators Should Watch During Implementation

The approved instruments are scheduled for a voluntary field test in the 2027-28 school year before the required statewide rollout in the 2028-29 school year. That timeline gives local educational agencies time to prepare staff, communicate with families, and plan how screening information will be used responsibly.

Training And Consistency Will Matter

The research notes state that the instruments and training materials will be provided by the CDE free of cost to local educational agencies for both the voluntary field test and the required statewide rollout. Cost-free access may reduce one barrier, but implementation quality will still depend on training, scheduling, language access, and staff confidence.

For classroom teams, one practical concern is consistency. A screening process can become less useful if different adults explain directions differently, rush children, or fail to consider whether a child understands the task. Training should help staff administer the screener as intended while still treating children warmly and respectfully.

Screening Is Only One Part Of Support

TK multilingual screeners can help identify children who may need support, but support itself happens through instruction, interaction, and family-school communication. A useful response might include oral language modeling, songs and chants, picture-supported routines, peer interaction, story retelling, and chances to answer in more than one way.

Educators should also be cautious about assuming that English growth requires less use of the child’s other language. The facts provided here do not establish a specific instructional model or prove which classroom approach will work best for every child. They do support a more limited conclusion: California has chosen age-appropriate screening tools for TK multilingual learners and has restricted high-stakes uses of the results.

California’s TK Language Screening Plan

California’s plan gives schools a clearer process for young multilingual learners while acknowledging that TK children need developmentally appropriate tools. Beginning in the 2028-29 school year, local educational agencies serving TK students must screen TK children within 30 days of enrollment when the Home Language Survey indicates a primary language other than English, based on the research notes provided.

For parents and educators, the most useful stance is balanced. TK multilingual screeners may help schools notice support needs earlier, but they should not be treated as a complete picture of a child’s abilities. Young bilingual children need adults who listen across settings, value family knowledge, and respond to communication attempts with patience and clear language.

The promise of California’s approach will depend on how carefully it is carried out during the 2027-28 field test and the 2028-29 statewide rollout. If schools use the tools within their stated limits, combine results with observation, and keep families involved, screening can become one helpful step in a broader early language support plan.
