Developmental screenings are a series of tests and assessments used to evaluate a child's development across various domains, including cognitive, social, emotional, and physical development. These screenings can help identify potential developmental delays or disorders early on, allowing for early intervention and treatment.

There are different types of developmental screenings, depending on the age of the child and the specific areas of development being evaluated. Some common types of developmental screenings include:

• Ages and Stages Questionnaires (ASQ): This is a series of questionnaires that evaluate a child's development across various domains, including communication, gross motor, fine motor, problem-solving, and personal-social skills. The ASQ is typically used for children between the ages of 1 month and 5 years.
• Modified Checklist for Autism in Toddlers (M-CHAT): This is a screening tool used to identify early signs of autism spectrum disorder in toddlers between the ages of 16 and 30 months.
• Denver Developmental Screening Test (DDST): This is a standardized test used to evaluate a child's development across four domains: gross motor, fine motor, language, and personal-social skills. The DDST is typically used for children between the ages of 1 month and 6 years.
• Social-Emotional Screening: These screenings evaluate a child's social and emotional development and may include assessments of temperament, attachment, and behavior.

It's important to note that developmental screenings are not diagnostic tools and should not be used as the sole basis for diagnosis. If a screening indicates that a child may have a developmental delay or disorder, further evaluation by a healthcare professional, such as a pediatrician or developmental specialist, is necessary to determine the best course of action.
