Below is the link for the National Association for the Education of Young Children. You will find many articles addressing some of your concerns or questions about the development of your child. This website is a wonderful resource for all families.
Below is the link for the Maryland Model for School Readiness. The Maryland Model for School Readiness (MMSR) is a statewide school readiness framework. It is defined by early learning standards that outline expectations for what all children should know and be able to do in all developmental areas by the end of kindergarten. The MMSR standards reflect the State Curriculum content standards, indicators and objectives. In addition, the MMSR Fall/Entry Exemplars were developed to provide assessment criteria or guidelines for the kindergarten, prekindergarten, and preschool-3 MMSR standards. The Exemplars have been designed using language that includes children with disabilities. I will be using the MMSR prekindergarten standards and indicators when assessing all of the children at the end of each marking period.
