In summary
The California Teachers Association has consistently opposed legislation that would require dyslexia screening for all students in early grades. Yet many teachers say early intervention is key to heading off later academic struggles.
For years, the California Teachers Association has opposed universal dyslexia screening for students, helping to defeat legislation that would have mandated it. And yet, many classroom teachers are advocating for all students to be tested.
As another possible legislative battle looms, the statewide teachers unionās opposition to mandatory screening continues to frustrate many educators. According to classroom teachers across the state, the California Teachers Associationās position will perpetuate a āwait-to-failā approach to reading instruction that forces educators to sit by while students fall further and further behind.
Dyslexia is a neurological condition that causes difficulties with reading and affects 1 in 5 people in the United States. But early screening and support can mitigate or even prevent illiteracy stemming from the learning disability.
Officials at Decoding Dyslexia CA, a grassroots advocacy group, say hundreds, if not thousands, of teachers working with students who struggle with reading support universal screening. The California Teachers Association doesnāt understand the benefits of screening all students for dyslexia, said Megan Potente, one of the co-directors of Decoding Dyselxia CA.
āI think thereās some misinformation,ā Potente said. āSome of the reasons for their opposition arenāt supported by the research.ā
Doug Rich, a veteran teacher and reading specialist at San Francisco Unified, said heās āgone rogueā and started screening all of his students for signs of dyslexia. He said testing is relatively quick ā taking less than 10 minutes ā but the results are crucial.
The test results can tell him where his students are struggling, whether it be sounding out letters or recognizing words. If all students were screened in kindergarten, Rich says, fewer would end up working with him.
āWe know so much about dyslexia,ā he said. āWe know the underlying causes. We have these simple tools that are efficient and accurate.ā

Reading instructors, education experts and neuroscientists all agree: early screening is one of the best ways to mitigate or even prevent the illiteracy that can be caused by dyslexia. Despite having some of the best experts in the field of dyslexia research, California remains one of 10 states that doesnāt require universal screening.
Thatās not for lack of trying. State Sen. Anthony Portantino, a Democrat from Glendale whoās dyslexic, tried and failed twice in the past three years to pass legislation that would have mandated universal screening for students in kindergarten through second grade. In February, he said he is trying a third time.
Although it has not taken a position on the latest bill, the California Teachers Association opposed Portantinoās last two bills. Claudia Briggs, a spokesperson for the union, said the associationās leadership team believed that bills would have caused āunintended harmful consequences.ā The associationās position is that universal screening will take valuable time away from instruction and may misidentify English learners as dyslexic by mistaking their lack of fluency in English for a learning disability. Briggs said the union would decide its position on the new bill in March.
Potente is optimistic about this yearās bill. It has 33 co-authors, more than double that of last yearās bill.

If the bill gets to Gov. Gavin Newsomās desk, itās not clear whether heāll sign it. Newsom, whoās also dyslexic, supported dyslexia research by funding UCSFās Dyslexia Center to the tune of $28 million in recent years. In 2021, he published a childrenās book based on his childhood experiences. His office, however, declined to comment on whether he supports universal screening.
In response to the unionās objections, a chorus of experts and classroom teachers, backed by a well-established body of research, contradict its arguments. CalMatters interviewed 10 teachers from across California who said screening students early prevents students from needing more intensive services when theyāre older. They also said universal screening would prevent English learners from being referred to special education because it would allow teachers to remedy early signs of reading challenges.
āTeachers are already spending an overabundance of time using other horrible assessments for reading,ā Rich said, referring to tests for reading comprehension or vocabulary. āAnd theyāre not getting good information.ā
A patchwork of screening
Some districts, like Pleasanton Unified in the Bay Area, already screen all students in kindergarten, first and second grades. In other districts, top officials encourage screening all students but havenāt adopted a universal screening policy.
Jennie Johnson, a reading intervention teacher for the Lancaster School District, 50 miles north of Los Angeles, said the district is in its first year of screening all students. Itās also training teachers on how to use the results from the screening to refine reading instruction.
Universal screening is even more critical now because pandemic-era learning loss resulted in so many students reading below grade level, Johnson said. Half of the fifth graders at her school are currently reading at a third grade level.
āWe are not surprised by the lack of literacy because thatās where our school typically is,ā she said. āBut the number of fourth and fifth grade students reading below grade level is alarming this year.ā
In other districts, itās up to individual teachers to advocate for screening their students. Kristen Koeller, a reading intervention teacher in the Cupertino Union School District, said she has to be strategic about which students get screening. When she recommends a student for a dyslexia screening, she said her supervisors encourage her to use other reading assessments that have been purchased as a part of the districtās reading curriculum. She said this ultimately discourages teachers from using screeners that havenāt been approved by district officials.
While district-approved assessments can help determine a studentās reading level, Koeller said they donāt test whether a student is at risk of dyslexia.
āYou can be a bit of a rebel,ā Koeller said. āBut you canāt just go around thumbing your nose at your boss. I just continue to advocate respectfully for the change Iād like to see.ā
Decoding Dyslexia CA includes a coalition of teachers like Koeller who are willing to buck both district policies as well as the California Teachers Association. They lobby state lawmakers and sponsored Portantinoās universal screening bills.
By at least one measure, most California voters support these efforts. A 2021 survey found that 87% of the stateās voters are in favor of a policy requiring universal early screening.
āI see this as a huge social justice issue. This āwait-to-failā model that weāre using in California is unacceptable.ā
Lori DePole, co-director of Decoding Dyslexia CA
Without a mandate, teachers say, whether a dyslexic student learns to read will be left to chance. That approach deepens inequities, as some students have parents who can afford private assessments and tutoring. But those who lack the resources are much more likely to become illiterate adults.
āI see this as a huge social justice issue,ā said Lori DePole, also a co-director of Decoding Dyslexia CA. āThis āwait-to-failā model that weāre using in California is unacceptable.ā
The California School Psychologists Association also supports screening all students between kindergarten and second grade, saying a small investment of resources earlier in a childās education can pay off exponentially.
āIf you catch them young, you can implement interventions that may prevent them from needing more intensive services later,ā said Melanee Cottrill, executive director of the California Association of School Psychologists.
The importance of early screening
Kristina Delgadillo, a middle school special education teacher at Visalia Unified in the San Joaquin Valley, said she regularly works with students who could have learned to read if they had been screened earlier. She said screening younger students is worth the relatively small time investment.
āIāve been assessing too many kids for the first time in fourth, fifth and sixth grade when I should have already been providing them services,ā she said. āI see kids fall through the cracks.ā
Delgadillo cited one study that found that it takes an additional 30 minutes a day for a kindergarten or first grade student with dyslexia to read at grade level. But if a student waits until fourth grade to be screened, it takes two hours a day.

Echoing the concerns of school psychologists, education experts say teachers can mitigate the illiteracy caused by dyslexia if they can detect the warning signs early. Even third grade can be too late, as students go from ālearning to read to reading to learnā in other subject areas. If teachers canāt get students reading at grade level by then, it means theyāll struggle with reading textbooks in social studies or word problems in math class.
āStudents donāt want to be in a classroom if they canāt read,ā said Jordan Paxhia, a special education teacher at San Francisco Unified. While effective reading instruction on its own canāt ensure a studentās success, universal screening is a crucial step to making sure all students can read at grade level.
āLiteracy may not be a panacea, but it certainly would give students more of a chance,ā Paxhia said.
Teachers say screening English learners is even more urgent. If left unaddressed, dyslexia could delay studentsā acquisition of English while they struggle to read their native language as well. And because they arenāt diagnostic tools, a red flag on a dyslexia screener wonāt mean a student will be sent immediately to special education. If a dyslexia screener detects a student is struggling with reading, a teacher will spend more time with the student. From there, the teacher and the school can provide more resources and services if necessary.
āIām not overly concerned about false positives,ā Paxhia said. āIt doesnāt mean they have dyslexia. And isnāt that a better use of our time than letting something go unnoticed?ā
Itās harder to reverse the damage for a student who isnāt screened early. High school and middle school teachers know this best.

Holly Johnson teaches ninth grade English at Santiago High School in Garden Grove. She works with students who read below grade level, but by the time they arrive in her classroom itās too late to remedy the effects of dyslexia. She doesnāt know for sure how many of her students have dyslexia, but she said itās clear that they never got the help that would have been provided had they been screened earlier.
āScreening can be done in high school, but itās so difficult,ā she said. āTheir relationship with school and their narrative has already been built.ā
Research shows that failing to read at grade level can have ripple effects for a studentās academic success as well as their mental health. Students who canāt read will struggle across all subjects in school. Theyāre less likely to graduate from high school and tend to earn less once they enter the labor force. But in the short term, illiteracy leads to anger and hopelessness for Johnsonās students.
āRather than being embarrassed about reading, theyāll pick a fight with the teacher,ā Johnson said. āThatās more cool than everyone knowing you canāt read.ā
A failure to screen students and help them in earlier grades means high school teachers like Johnson must not only teach them how to read but how to rebuild their identities as students.
āIf we can get these kids diagnosed, their problems wonāt be as big,ā she said. āAll of it can be nipped in the bud.ā

Why California still doesn’t mandate dyslexia screening
California is one of only 10 states in the country that does not require schools to screen children for dyslexia. Experts agree early diagnosis is key to helping dyslexic students learn to read, yet the statewide teachers union and others have blocked those efforts.
