Is New York State exceptional?

337 J.H. Bishop et al. Economics of Education Review 19 2000 333–349 requirement is than the current Regents Competency Tests. It is clear that many students will not be able to pass these exams without working a good deal harder. Do longer school days cause more students to drop out? If the current voluntary Regents exams have pushed up dropout rates without improving achievement, the case for requiring them is weakened. The next part of the paper examines these issues by estimating cross-section models predicting test scores and dropout rate indicators and testing the “New York State is exceptional” hypothesis. State level means for four outcomes will be analyzed: SAT-I test scores; 8th grade NAEP mathematics achievement scores; the school enrollment rate at age 17; and the high school graduation rate. The Regents also believe that setting higher standards will help graduates to be more successful in both college and the labor market. Section 3 of the paper examines the hypothesis that students who avoid remedialbottom track courses andor graduate from high schools that require minimum competency exams are more successful in the labor market and more likely to enter and survive in college. These issues will be addressed by measuring the effect of MCEs and the taking of remedial courses on college attendance and labor market success of high school graduates in three nationally representative longi- tudinal surveys: NELS88, HSB and NLS72. Section 4 of the paper takes a more ground-level view of the effects of mandated curriculum-based exit examin- ations on teaching practice and school culture by inten- sively studying 10 schools that successfully shifted to an All-Regents curriculum in the early 1990s. The study is based on interviews with teachers, administrators and school board members. Each school is different but a theme that runs through all the responses is the need to increase the amount of time that teachers spend inter- acting with struggling students. Lessons for other school districts that are trying to respond to the Regents man- date are drawn. 2. Is New York State exceptional? New York’s students are more disadvantaged, more heavily minority and more likely to be foreign born than students in most other states. Among northern states, only Maryland, Delaware and Illinois have a larger share of African–American pupils. Nationwide, only Califor- nia has a higher share of its population foreign born and only California, Texas, Arizona, New Mexico and Color- ado have larger Hispanic population shares. Since test scores are lower for foreign born and minority students and for students from low-income backgrounds, family background must be taken into account when one com- pares student achievement levels and dropout rates of the 50 states. Considering the high incidence of at-risk children, New York students do remarkably well. The proportion of students taking algebra, calculus, chemistry and phys- ics is generally above national averages. A larger pro- portion of New York’s 11th and 12th graders are taking and passing 9.4 AP exams in English, science, math or history than any other state except Utah NEGP, 1995, Vol. 2. 2.1. Impacts on SAT-I scores Graham and Husted’s 1993 analysis of mean SAT test scores in the 37 states for which ETS published data on the characteristics of test takers found that New York State students did better than comparable students in other states. They did not, however, test the statistical significance of the New York State effect and used an unusual log–log specification. Table 1 presents the results of a cross-section regression predicting 1991 mean SAT-M + SAT-V test scores for the 37 states for which data are available. With the exception of the dummy variable for New York State, all right-hand side variables are proportions—gen- erally the share of the test taking population with the characteristic described. Clearly, New Yorkers do sig- nificantly better on the SAT than students of the same race and social background living in other states. When this model is estimated without the NYS dummy vari- able, New York has the largest positive residual in the sample. The next largest Wisconsin positive residual is 87 of New York’s residual. Illinois and Nevada have positive residuals that are about 58 of New York’s value. Arizona, California, Colorado, Florida, New Mex- ico, Ohio, Rhode Island, Texas and Washington have negative residuals greater than 10 points. Many of these states have large populations of Hispanics and recent immigrants, a trait that was not controlled in the analysis. This makes New York’s achievement all the more remarkable when one considers that Hispanics and immi- grants are a large share of its school children. 4 For individuals, the summed SAT-V + SAT-M has a standard deviation of approximately 200 points. Conse- 4 New York State has had Regents exams since the middle of the 19th century. Consequently, selection bias or reverse causation i.e. Regents exams are a result of a strong taste for education by the people of New York State are not plausible explanations for the current positive relationship between Regents exams and high achievement or between Regents exams and high levels of public investment in K-12 schooling. The theory Bishop, 1996, 1999 specifies that exam systems influence public decisions about investment in K-12 schooling as well as the standards set by teachers and student effort. Consequently, one should not control for spending, teacher qualifications, class size and other school input variables when one is attempting to measure the total effect of an exam system. J.H.

Bishop et al. Economics of Education Review 19 2000 333–349 quently, the differential between New York State’s SAT mean and the prediction for New York based on out- comes in the other 36 states is about 20 of a standard deviation or about three-quarters of a grade level equiv- alent. Adding the teacher–pupil ratio and spending per pupil to the model, reduces the NYS coefficient by 25. It remains significantly greater than zero, however. The significant coefficient on teacher–pupil ratio suggests that heavy investment in K-12 schooling in New York State possibly stimulated in part by the Regents exam system may be one of the reasons why New York State students perform better than comparable students in other states. 2.2. Impacts on mathematics achievement of 8th graders The New York is exceptional hypothesis can also be tested by analyzing data from the 1992 administration of the NAEP mathematics test to representative samples of 8th grade students in 41 states and the District of Colum- bia. The states not participating in the 1992 NAEP were Alaska, Illinois, Kansas, Montana, Nevada, Oregon, South Dakota, Vermont and Washington. As with the analysis of SAT scores, state test score means were regressed on variables controlling for the socio-economic characteristics of the state’s population and a dummy for New York State. The five variables that controlled for student background were: the proportion of people under age 18 who live in poverty; a schooling index for the adult population; percent foreign born; percent public school students who are black; and percent public school students who are Hispanic. Means and standard devi- ations for all variables are given in Appendix A. The results are presented in Table 2. Parents education, the poverty rate, percent black and percent foreign born all had significant effects on math achievement in the expected direction. New York State’s mean NAEP math score was a statistically significant 9.6 points or about one grade level equivalent above the level predicted by the other variables in the regression model. This coef- ficient was significant at the 5 level on a two tail test. One of the ways Regents exams might improve per- formance is by inducing the public to reduce the pupil– teacher ratios, keep schools open longer and assign more homework. Models were estimated that included these variables. While coefficients on these variables had the expected sign, only one—hours of instruction per year— came close to statistical significance. With only 42 obser- vations, however, the power of these tests is low, so insignificant coefficients are to be expected. While stat- istically insignificant, the estimated impact of instruction hours is large enough to be substantively important. The point estimate implies that a 10 increase in scheduled hours will increase 8th grade math scores by about a third of a grade level equivalent. 2.3. Impacts on high school dropout rates Table 2 also presents the results of cross-state regressions predicting school enrollment rates at age 17 and high school graduation rates. The fear that the cur- rent New York State Regents exam system is pushing students out of school is contradicted by the data. New York State’s high school dropout rate is not significantly different than that of other states with students from similarly disadvantaged backgrounds. Longer school days and longer school years are not associated with higher dropout rates. Indeed, dropout rates appear to be lower in states that have more hours in the school year. A 10 longer school day or school year is associated with a 1 percentage point higher enrollment rate at age 17 and a 3.5 percentage point higher high school gradu- ation rate. A 10 reduction in the pupil–teacher ratio is associated with a high school graduation rate that is 1.5 percentage points higher. More homework also has a sig- nificant positive relationship with graduation rates though not with enrollment rates at age 17. This pattern of results is consistent with the findings of the research on Accelerated Schools and other efforts to raise stan- dards. 2.4. Does New York State invest more in K-12 education? The theory predicts that the existence of CBEEES will induce New York State to spend more on K-12 education and focus that spending on instruction. Among the 50 states and the District of Columbia, New York ranks third in average teacher salary, third in current expendi- ture per student and first in the share of the current expenditure allocated to instruction NCES, 1998. New York teachers are also more likely to have a masters degree than the teachers of any state except Connecticut, Kentucky and Indiana. 5 5 The theory predicts that exit exam systems will induce school administrators to make policy changes that they believe will increase student learning Bishop, 1996, 1999. Whether each and every change they make actually increases learning is an entirely different matter. Most educational leaders are either unaware of research findings that masters degrees have little effect on student learning or do not accept the findings. The New York State Board of Regents has just proposed an increase in the minimum number of college courses in their subject of certification that new teachers must have and an increase in the number of hours of continuing education that incumbent teach- ers must get annually. They gave the new higher standards and five Regents exam requirements as their primary reason for the change. J.H. Bishop et al.

Bishop et al. Economics of Education Review 19 2000 333–349 Clearly, New York invests a great deal in its K-12 education system. If the cause of the high spending were high costs of living, a strong general commitment to edu- cation or legislative profligacy, we would expect spend- ing to be high on both K-12 and higher education. This is not the case. New York ranks second in the ratio of K-12 spending per pupil to higher education spending per college student and third in the ratio of K-12 teacher salaries to college faculty salaries NCES, 1998.
