The process and purpose seems clear for many children, however in practice it is important to consider the nearly 12 million children who speak a language other than English at home. For these children careful consideration of English language proficiency and the language of reading instruction need to be taken into consideration. English proficiency will influence a child’s ability to understand task directions, the vocabulary used in the test, and the background knowledge necessary to respond appropriately to many test items, especially when measuring vocabulary development. The language of reading instruction will directly impact the development of children’s code-based literacy skills.
Differentiating Between Language and Literacy Skills
When screening for reading problems, it is important to distinguish between how language and literacy skills are measured. Language skills are learned through everyday interactions across home, community and school settings. Reading skills are most likely formally acquired through instruction and are therefore instructionally dependent. This means that if a child is not instructed to read in a language, a reading screening in that language is unlikely to yield an accurate estimate of their reading ability, even if they are more proficient in that language.
Home and Community Language Exposure
Children develop language through frequent and regular exposure to that language across naturally occurring routines. Therefore, teachers should ask families to complete a home language survey to gather information about how much each is spoken at home to better understand a child’s current language exposure. At school entry by law, these children are administered an English proficiency test, and teachers should consider the child’s level of English proficiency when interpreting reading screening results. The multilingual child’s score on an English reading screening cannot be interpreted accurately unless the teacher has information about the child’s exposure to English and their English proficiency.
Language of Instruction
In general, children do not learn to read in a language in which they have never received any reading instruction. For most children school is the primary context in which they formally learn to read. Therefore, when screening multilingual students, information is needed not only about the child’s exposure to their heritage language and English, but also the language of reading instruction. It is no mystery that children learn what they are exposed to and therefore these contextual factors are critical to consider when evaluating the performance of a multilingual student on any reading screening battery.
Two Real Life Scenarios
Trinh is a Kindergartener whose family speaks Vietnamese at home, and she is growing up in a San Francisco neighborhood with many Vietnamese families. She is in in an English-only classroom, and while her English abilities are emerging quickly, she is clearly more dominant in Vietnamese. When Trinh is screened in English for reading problems in October, she scores in a range that is below benchmark. There are no assessments available in Vietnamese. Trinh’s family has completed a language survey and the teacher knows that she is primarily exposed to Vietnamese in her home. The teacher also has access to her English proficiency testing and knows that Trinh is in the emerging stage of English acquisition. Her teacher therefore understands that Trinh should not be considered as having low reading development, but rather as needing more time in English instruction to develop reading skills. Trinh’s teacher can work closely with the specialist who serves English learners to better understand Trinh’s English development and learn strategies to support her comprehension of reading instruction in the classroom. Trinh’s reading development should be monitored to document her rate of growth as she begins the process of formally learning English while also learning how to read in English.
Now let’s consider Mateo who is in 2nd grade. His family is from El Salvador, and they use more Spanish than English at home. He has been enrolled in a dual language program in Washington D.C. since kindergarten where their goal is to support biliteracy development. There are many assessment options to screen Mateo in both English and Spanish. Reading screening measures are now available in both languages that can accurately identify children who are in need of additional instructional support in either language. Mateo scores within normal limits in Spanish and only slightly below benchmark in English. Given that Mateo’s family speaks more Spanish than English at home and that he is learning to read in both languages there is likely no reason for concern about Mateo’s reading development. Over time in the dual language program, he is likely to balance out in his skill development.
