Observation and assessment are most effective when a. tools are appropriate for the children in your setting and meet professional requirements for quality. b. the state has selected them as an appropriate tool for you to use. c. parents select the tools you use. d. assessments are formal and gather focused information.

the answer is (A). tools are appropriate for the children in your setting and meet professional requirements for quality.
Observation and assessment will be the most efficient when you give as much freedom to the children as possible. We will never know whether the children reveal their usual actions if we put them in an environment that is strange and unnatural for them.
