  21. Importance Information is key to any decision-making process. This process is only as good as the data used to inform it.

  22. Importance • Possible consequences of inferior data quality include • Inefficiency • Loss of time • Lack of confidence in using the data • Poor decisions

  23. Importance Assessing the data quality at any organizational level is the first step to plan for improvements. The National Center for Education Statistics (NCES) has a self-assessment tool for schools and districts.
