Answer:
Observation is just one form of informal assessment, evaluation, or appraisal.
The person who would most likely know what assessments are required is the educator or teacher.
Formal assessments are often structured, conducted in a way that captures child learning in a set way.
Informal assessment captures children’s learning in the context of their play and participation in activities.
Standardized assessment includes the way you administer the assessment to the children in your setting.
Standardized assessment also includes the way you interpret the results from the assessment.
validity means that assessment tools measure the constructs and variables as they define it.
reliability means that the assessment is consistent regardless of the children assessed or the teacher who conducts the assessment.
When you're looking at the evidence-base of an assessment, consider whether the population is the same as the children in your setting.
One of the critical things to keep in mind when looking at lists of assessment tools is to determine whether the tool is an ongoing assessment tool or a diagnostic or screening tool.
