Using the ECERS 7-point scale, the mean value of this index in their sample is 4
These studies have several limitations. If the relationships estimated in their model have changed since 1989, these estimates will differ from what Thomaston loans we would expect to find using current data. Changes in quality made now may affect total costs in a different manner.
Also, the data include only accredited centers. If these centers have cost functions that systematically differ from unaccredited centers, the estimated results will not apply to those centers. If, for example, one is most concerned with improving poor quality child care, and such care is more likely to be found in unaccredited centers, these estimates may not provide an accurate depiction of the costs of doing so. The sample also only includes data for care of 4- and 5-year-old children. Because of differences in providing care for other age groups, the relationship between improving quality and costs for centers that provide care for other age groups ple includes data from many states, 70 percent of the centers surveyed were in the South and the Midwest. The results therefore may not be nationally representative.
