The awareness and knowledge of developmental milestones among health practitioners need to be enhanced to better enable early identification and intervention with children who have delays in development, intellectual deficit, and developmental disabilities and are residents in low-and middle-income countries. To meet this end, a simple one-page…

The issue of identifying reading difficulties and disabilities in English language learners (ELLs) is a complex one. It is an area that draws on the diverse disciplines of first- and second-language acquisition, literacy, English language learning, and reading, including differences and disabilities research.
