There are two necessary skills for any line staff worker in a juvenile detention center, a juvenile correctional facility or an adult facility serving youth—the ability to observe behavior and events accurately and the ability to record them in a clear and concise fashion. Newly hired staff may or may not have these skills at an adequate level. They must receive relevant training to develop the desired capacity. Furthermore, there is no guarantee that the direct care worker will somehow learn sufficient skills in these areas by himself or herself.
