Response Rates

Unit response rates. The unit response rate indicates the percentage of sampled cases that met the definition of a complete interview. The weighted SASS unit response rate was produced by dividing the base-weighted number of respondents who completed questionnaires by the base-weighted number of eligible sampled cases.7 Table B-1 summarizes the base-weighted unit response rates for each survey type. Because response rates vary between surveys, it is possible not to have information for all the components related to a particular school. For example, it is possible that a district does not have a corresponding school record or there may not be a principal record for every school.
