In a raging debate, leading researchers in reading education are speaking out in favor of keeping Common Core Kindergarten Literacy Standards. Their message? It’s perfectly fine for five year olds to play and learn to read in school!
Perhaps Dr. Tim Shanahan said it best: “There are not now, and there never have been data showing any damage to kids from early language or literacy learning.”  As a former first grade teacher who is currently Distinguished Professor Emeritus of urban education at the University of Illinois at Chicago, past president of the International Reading Association, former member of the National Reading Panel, and appointee to the Advisory Board of the National Institute for Literacy, he’s qualified to weigh in on the topic.
Shanahan cites the following studies from Developmental Psychology and the Journal of Educational Psychology showing the long-term benefits of early literacy achievement. “Early reading performance is predictive of later school success,” he says when listing these psychological studies and more: Cunningham & Stanovich, 1997; Duncan, Dowsett, Claessens, Magnuson, et al., 2007; Juel, 1988; Snow, Tabors, & Dickinson, 2001; Smart, Prior, Sansor, & Oberkind, 2005. 
In addition he reminds us of a slew of studies “showing the immediate benefits to literacy and language functioning from kindergarten instruction” which are summarized in the National Early Literacy Panel Report (available on line) which he co-chaired.
Other Heavy Lifters in Reading Education Weigh In
Most reading educators, including myself, recommend teaching reading and writing in a play-based academic kindergarten. There need not be a “play” versus “academic learning” battle over kindergarten CCSS standards. To argue that children need to play in kindergarten is a non sequitur and a nonstarter in this debate. In fact, the best models of kindergarten learning including the highly regarded Montessori model, the Chicago Child-Parent Center program, and the High/Scope Preschool Program based on the well-known Perry Preschool studies, and others, teach early literacy skills as well as social and emotional learning through play. 
Teach beginning reading for kids who are not getting it at home.
Dr. Deborah Stipek. Dean of the Graduate school of Education at Stanford made the point in a quote this month in the New York Times: most children from affluent and middle-class families get early literacy experiences at home or in preschool. For example, two-thirds of the kids who enter kindergarten can identify upper and lower case letters.  “Middle-class parents are doing this anyway,” says Stipek [teaching letters; giving preschoolers book experiences and exposure to literacy] “so if we don’t do it for kids who are not getting it at home, then they are going to start at an even greater disadvantage.” 
Those of us who work directly with kindergarteners in schools see legions of children in low income “free and reduced lunch” schools who enter kindergarten having rarely been read to and having little knowledge of letters or sounds. Unlike kids from more affluent districts, when these kids enter kindergarten they often can’t tell you the name of a favorite book or write their own name. Some can’t hold the book correctly to turn the pages. They can’t name common zoo animals or farm animals or exhibit the kind of background knowledge and vocabulary needed for comprehension.
Some proponents of delayed reading support their stance by pointing to high-achieving students in Finland where reading starts much later. It’s not a valid comparison due to Finland’s very different social structure, superior system of teacher education, much less variable demographics, and most importantly, due to the huge differences in the spelling systems of two very different languages. Giving poor kids in America Finland’s “gift of time” to learn to read sucks poor English-speaking kids into early reading failure.
Dr. Nell Duke, a professor of Literacy, Language, and Culture at the University of Michigan and a member of the International Literacy Association’s Literacy Research Panel weighed in on this topic over the last month. She blogs for the ILA Literacy Research Panel and connects over 300,000 ILA members around the world with research relevant to policy and practice. In her two-part series entitled “Addressing the CCSS for Kindergarten in Developmentally Appropriate Ways,” Dr. Duke shows that all six literacy standards for kindergarten “can be addressed through instruction that involves neither long hours of drill nor worksheets.” 
In addition to the International Literacy Association which has the world’s largest membership for reading professionals, the large and respected National Association for the Education of Young Children (NAEYC) stands behind teaching reading in kindergarten. In Basics of Developmentally Appropriate Practice: An Introduction for Teachers of Kindergarten, the authors state that by the end of kindergarten “most children will be reading simple and predictable text.” (NAEYC pg. 104)  Reading simple and predictable text comports with the CCSS’s Fluency expectation: “Read emergent-reader texts with purpose and understanding.”
The attack on Common Core kindergarten standards and the claim of no long-term benefits put forth in the non-refereed opinion report by the Defending the Early Years and the Alliance for Childhood advocacy groups  is misguided, a misinterpretation, and unsupported.
Children—especially low-income children—should begin to develop both reading and writing skills in kindergarten as expected in CCSS standards and avoid falling behind. While it’s true that even in America some kids with delayed reading succeed, they are rarely lower-income students.
Debate, action, and advocacy to improve kindergarten education in America is sorely needed. But we will better serve our kindergartners by untangling the knot tied to CCSS kindergarten standards.
