The CSSP has two main objectives; identifying parameters with low inter-organization agreement, and estimating measurement system variability. The identification of parameters with low agreement is used as part of the overall Quality Assurance program. Laboratory and program personnel use this information to investigate possible causes of the differences, and take action to increase agreement if possible. Later CSSP results will document any improvements in inter-organization agreement. The varability estimates are most useful to data analysts and modelers who need confidence estimates for monitoring data.
