... NCES notes24 that the adaptations for assessment administration postCOVID-19 may suggest substantial increases in administration costs that are not yet understood. It is important to note that a widespread use of local administration is likely to reverse these extra cost increases, since special procedures for going into the schools will not be necessary if NAEP staff do not go into the schools.

... . That is, the innovations discussed in this chapter potentially provide other ways to reduce administration costs, but a successful transition to local test administration would substantially reduce field costs, which would substantially reduce the possibility for these innovations to save money.
From page 58...
... As discussed in Chapter 5, NCES currently estimates the savings from the use of local administration for the mandated assessments by a cost reduction from $3,500–4,500 per school in 2024 to $2,000–3,000 in 2030 over a base of 15,500 schools. The expected savings from two-subject administration produces further savings by reducing the number of sampled schools by one-third, initially to 13,500 in 2028 and then to 10,500 in 2030.7 In 2028 there would be 2,000 fewer schools when the per-school 2 Interestingly, NAEP did try a three-block, two-subject design in the 1985–1986 adminis tration (Beaton et al., 1988)
From page 59...
... If the panel's estimate is correct that local administration has the potential to reduce administration costs by about 80 percent, then the remaining average annual administration costs in a decade should be roughly 20 percent of their current values: $7.2 million for the assessments and $1.0 million for the pilot administration.9 If 90-minute tests can reduce these administration costs by one-third, that might represent an annual average savings of $2.7 million by 2030, which is 1.6 percent of NAEP's overall budget. The potential savings in the next few years from using tests with 90 minutes for the cognitive items -- before local administration is implemented -- would be much larger because the overall administration costs are currently much larger.
From page 60...
... RECONSIDERING THE SAMPLE SIZES NEEDED TO ACHIEVE NAEP'S PURPOSES Test administration costs -- particularly in the current model -- are directly related to the size of NAEP's sample. If it is possible for NAEP to perform its mission with smaller sample sizes, there could be substantial cost reductions.
From page 61...
... Because this last question compares two mean differences, this is a "difference in differences." Then, the statement mentions differential progress "among jurisdictions and subpopulations." This parameter amounts to asking, for example, whether gender gaps are increasing more in one state than another. Because this compares a gap over time, in two different states, this is sometimes called a "triple difference." As an example, consider the 2019 NAEP estimate for the performance of English-language learners in Shelby County, Tennessee, which is one of the urban districts included in the Trial Urban District Assessment program.
