In 1987, a survey report by J. Cannell was published criticizing state reports based on national standardized testing of elementary school students that indicated that all 50 states were above the national average. This phenomenon--known as the "Lake Wobegon Effect"--is analyzed. Technical problems with the study are considered. (TJH)

A Friends for Education (FFE) survey revealed that no state is below the norm at the elementary school level on six nationally normed commercially available achievement tests. Tests use a norm group from the past for comparison, but FFE suspects that inaccurate initial norms and teaching the test may cause high scores. (SLD)

Officials of the United States Department of Education conclude that the pervasive "above average" achievement reported by J. J. Cannell (1988) results from a combination of testing practices and procedures among school testing programs. Causative factors of this paradox, dubbed the "Lake Wobegon Phenomenon," are discussed.…

Representatives of the Riverside Publishing Company discuss the "Lake Wobegon Phenomenon," the reported "above average" achievement of most elementary schools nationwide that was discussed by J. J. Cannell (1988) of the Friends for Education. More appropriate use of normative comparisons and more complete reporting of test…

The time-bound nature of test norms is discussed in light of the report of J. J. Cannell (1988) that a large majority of elementary schools report above average achievement on national achievement tests. Generally increasing levels of achievement are deemed to be responsible for this phenomenon. (SLD)

Recognizing the concerns raised by J. J. Cannell (1988), Science Research Associates (SRA) defends its norms. Trends in curriculum need to be monitored in addition to students' achievement levels. New norms are needed only when there is a significant shift in curriculum or student performance. (SLD)

Despite the skepticism of J. J. Cannell (1988) that commercial test scores reveal much about the real achievement level of students, there is ample evidence that at least some of the gains observed on standardized tests are legitimate. Standardized scores should be greeted with healthy skepticism when high, but taken very seriously when low. (SLD)

In response to J. J. Cannell's (1988) discussion of the reported "above average" achievement of the vast majority of public school systems nationwide, the nature of national norms is discussed. The public must be better informed about the interpretation of test results. (SLD)

The developer of the Comprehensive Tests of Basic Skills scaling responds to Hoover's attacks on Thurstone and item response theory scales (TM 510 173). While agreeing that grade equivalent (GE) scores are presently the most appropriate developmental score for reporting elementary grade achievement tests, limitations and inconsistencies in the GE…

Four publishers responding to the previous discussion agreed that American elementary achievement has improved, but evidence presented by the Secretary of Education confirms that few real improvements have occurred since "Nation at Risk." Commercial achievement tests provide falsely high scores (the Lake Wobegon Effect). (SLD)

Grade equivalent (GE) scores for elementary school achievement tests are defended in response to efforts to ban their use. Equal interval developmental scoring methods for the Sequential Tests of Educational Progress and the Comprehensive Tests of Basic Skills are criticized. (BS)

The author addresses issues raised by Burket (TM 510 174) about the Iowa Test of Basic Skills scaling procedures. Further reasons for his criticism of Thurstone scale scores and item response theory scale scores for elementary school achievement tests are given. (BS)

Results of a 1987 report indicating that elementary students of all states were above the national average are assessed. Issues addressed include teaching for standardized tests, the effect of teaching on national norms, and alternatives available to protect the integrity of instruction and the validity of normed test scores. (TJH)

Results of a 1987 report--indicating that elementary students of all 50 states were above the national average--were assessed via 2 national mail and telephone surveys. Although results of data for 35 states support the general findings of the 1987 report, it appears that more specific results are less sensational. (TJH)
