One of the problems with building a policy analysis data base is that the disparate data elements must be linked by individual student record. Hence, information from the admissions data base had to cross-link to the state-wide high school data base. For this project, the data indicators from the TEA high school data base were identified by a high school code and linked to a different high school code used during the admissions testing phase. A cross-link data base was constructed in order to bring the two sets of data into a common database for the next stage of the policy research, the analysis of data. Selecting data analysis techniquesIn the third stage of this policy analysis research project we selected the appropriate statistical analyses for building and analyzing the academic merit and adversity indicators. The selection of an appropriate data analysis technique is a function of many factors, but one of the most important is the form of the data comprising the policy data base. The form of the data elements limits the statistical analysis, yet policy analysis research routinely demands data in many different forms, much of it is categorical or qualitative in nature. Consequently, many of the traditional inferential statistical methods could not be used. For this project, we used the exploratory data analytic tools suggested by Tukey (1977). For each of the data elements, we generated simple frequency distributions to understand the range and shape of the data. The goals of the program were to identify no more than 5% of the student applicants for possible financial scholarship awards, yet within that small group we had to make very discriminating decisions. Hence, the adversity index had to be constructed in such a way as to set a cutting score at a high level, yet provide a way to spread students across three scholarship categories. To achieve the desired shape and form for this index, we looked at each data element and assigned points giving the top 5% of the data distribution a large number of points. The next 10% of the students in the distribution would receive fewer points, the next 10-15% only a small number of points and the bottom 70-75% of any given data distribution would receive almost no points. For example, we generated the distribution for the percentage of students participating in the federal lunch program within the Texas high and assigned points as shown in the table below. If students attend a high school in which more than 70% of the students were served by the federal lunch program, they received a larger number of points because that high school represented a more "adverse" environment. This kind of point assignment was made for each data element. The indicators, the points assigned and the percentages of students within each point category are shown in Table 2. Table 2

The points were summed within each of the three broad categories - parent, school and peer performance indicators -- to provide an overall adversity index that ranged in value from 0 to 69. That distribution was then used to determine three award levels. These three award levels, called Extreme, Substantial and Moderate Adversity were combined with the academic merit indicator of high school rank. Hence, students who were in the top 5% of their graduating class and in the top 5% of the adversity index would receive a $5,000 renewable scholarship for four years. Students in other combinations of adversity or high school class rank would receive differing amounts of scholarship money. Table 3 below shows the possible categories of financial aid award.

In the next stage, called policy analysis simulation, we assigned points to each adversity indicator based on the percentage of students that fell within certain data distribution values. Through repeated iterations of assigning points, re-examining the data distributions and adjusting the number of points assigned, we achieved a balance between the sub-components of the family socioeconomic, the school and the peer performance indicators. This is a particular strength of policy analysis research and will be described in some detail in the next section.
The fourth stage in conducting policy analysis research is to conduct policy simulations by creating the conditions under which the new policy might be applied, examining the results, adjusting the policy to further refine the possible outcomes and then re-applying the "new" policy and re-examining the outcomes again. Figure 1. shows a graphical example.
Figure 1. Policy simulation analysis flow chart.
The number of simulations is unpredictable and depends on how well the policy produces the expected results. For the financial scholarship program, points were assigned to the data elements and new cutting points established numerous times. By applying the points to an entire population of admitted students, the number of awards and the amount of money could be related to the pool of potential recipients. In addition, part of the simulation provided for the opportunity to generate statistical profiles of these potential recipients. The statistical profiles were based on the data elements comprising the selection criteria for the scholarships. Hence, at the end of each policy simulation, the potential pool of award recipients could be compared with those who had not qualified under that simulation analysis. These statistical profiles allowed the decision-maker and research policy analyst an opportunity to "fine tune" the outcomes, not only in the number of students who received awards, but also in terms of the selection criteria defining the adversity index. If the criteria selected too many students for a given category of scholarship recipients, the cutting points for the award selections were adjusted. Likewise, if the policy simulation analysis provided awards to the "wrong" students, the number of points could be re-assigned to yield a more desirable mix.
These policy simulations form the heart of policy analysis research because the results of "applying" the policy to a particular group of students can be evaluated, adjusted and re-applied before having to make a "final" decision about the policy standards. In the case of the financial scholarships, we were able to estimate the number of students qualifying within a pool of admitted students. In addition, a statistical profile of the potential award recipients allowed the decision-makers an opportunity to make judgments about the "correctness" of their policy decisions. That is, were the "right" students ending up with the awards? At one point during the policy simulation analysis for this project, we shared the results with the President and executive officers of the University. They raised questions about how points were assigned to students when they came from a single parent rather than a two-parent family. We examined the statistical profile and made an adjustment to the points for the estimated family. We then tried the "new" point system for the entire admitted class to see if a different point weighting system provided a more equitable selection of students from single-parent families. Arriving at an appropriate number of points for this category of student within the larger population required several iterations, but ultimately led to an acceptable outcome for the decision makers. Without these many simulations of the policy, the final outcome for a dramatically new and different approach to select scholarship recipients would not have been possible.
A brief example from one stage of the policy simulation analysis is provided here to illustrate how changes in the policy standards yielded different policy outcomes. Our goal was to achieve two important outcomes. First, because we had a finite amount of money to award, we had to identify a specific number of students for each award type. Second, we wanted to achieve a particular balance among the contributing family, school and peer performance factors. By adjusting the total adversity index cutting score used to define the low, moderate, substantial and extreme levels of adversity, we could modify the number of students who qualified within each high school rank category. By adjusting the point values for the data base elements used to define the three subscale categories, we could change the relative importance of the family, school and peer performance in the final adversity numerical score. During the initial iterations, we manipulated the point values to achieve the type of balance among the contributing factors we thought was most important. Once we achieved about the right mix among the three components, we worked to adjust the adversity index cutting score in combination with the high school rank to achieve the number of students within each award category.
This example shows data from the "middle" of the policy simulation analyses. The first table shows the number of students and the mean adversity index subscale scores by high school rank. This table was used to summarize how many students fell into each potential financial aid award category and to show the average value of the adversity index subscores. These latter values were examined to determine if the relative amount of weight given to the parental factors, the school factors and the peer performance index were in about the right proportion. During these two iterations, we intentionally tried to reduce the number of students in the "extreme" adversity categories within each high school rank category. By raising the total adversity index cutting score, we reduced the number of students with extreme adversity from the top 5% of the high school class eligible for the $5,000 scholarship from 298 to 221. The relative mean values of the three contributing factors to the adversity index - the parent index, the school index, and the peer performance index - changed very little, though the school index changed more than the other two factors.

Through repeated iterations we were able to identify an appropriate number of students with the type of qualities we were seeking to match the amount of money available. The next stage, validating the policy, is important if we want to evaluate how well our new policy standards worked.
While the policy simulations allow the policy to be applied and evaluated "before" it is implemented, all possible outcomes can not be anticipated. Ultimately, the test of time must be applied and the "real" results gathered and evaluated. If the outcomes are successfully achieved, the policy may remain in effect without further modification. However, the more likely scenario is that unanticipated outcomes occur and additional refinements must be made in the policy.
One way to validate the results of the policy analysis project was to generate "profiles" of students selected for the awards. These profiles helped answer the question, "Did we get the 'right' students?" The goal was to select students with economic need who would do well in college. Though the Hopwood decision and subsequent interpretation prevented the use of race as a criteria in the selection of scholarship recipients, the intent of the policy was to pursue the goal of increasing the ethnic diversity of the campus as well. By identifying economically disadvantaged students, we expected to include a substantial number of minority students. By comparing the demographic profiles of the scholarship recipients with the profile of the first-time entering freshmen who did not receive this scholarship, we were able to evaluate whether our policy simulations produced the expected results.
Table 5 shows the data for the Presidential Achievement Scholarship for the 1997-1998 year. When we examined the aggregate statistics for the variables contributing to the Adversity Index Point system, we found that socio-economically disadvantaged students were identified. For example, nearly 52% of the mothers of the PAS students stopped their education with a high school degree or less compared to less than 15% of the other freshmen. In contrast, nearly six out of 10 (59%) of the non-PAS students' mothers completed at least a four year degree compared with only 16% of the PAS recipients. More than 75% of the non-PAS students' fathers had at least a four-year college degree compared with only 16% of the PAS students' fathers. The family income of the parents of these two groups differed dramatically as well. Using the Adversity Index, we clearly identified economically needy students. For example, 76% of the mothers of PAS students earned $25,000 or less compared with 52% of the mothers of regular students. Approximately, 40% of the non-PAS students' fathers earned more than $55,000 dollars, while only 11% of the PAS students' fathers earned that much.

Another way to validate our policy was to examine the academic performance of these students in the classroom. Because more weight was given to financial need and less weight given to academic merit, we could not predict how well these students would fare in the classroom. The data in Table 6 show the academic outcomes of the PAS students versus the Non-PAS students.

When compared to the non-scholarship holders, the recipients had lower standardized test scores, but higher high school class rank. Because class rank was weighted nearly twice as heavily in the predicted grade point average than the SAT test score, the PAS students were predicted to do slightly better than the non-PAS students (PAS=2.90 and Non-Pas = 2.82). These students had a history of overcoming the adversity of a lower socioeconomic status, but they may have attended a school that did not prepare them for college. One type of evidence used to evaluate the policy was whether or not these students would succeed academically and return for their sophomore year. At the end of the first year, the PAS students earned a 2.78 GPA, slightly lower than the predicted GPA of 2.90, while the Non-PAS students earned a 2.87 GPA which was just slightly higher than their predicted GPA of 2.82. In terms of the retention indicators, the percentage of PAS students who returned to start their sophomore year in good academic standing was nearly identical to the Non-PAS students (79.9% versus 79.7%). A slightly larger percentage of PAS students than Non-PAS students returned on academic probation (6.6% versus 5.6%). In addition, a slightly larger percentage of PAS students than Non-PAS students left on academic probation and or dismissal and a smaller percentage left in good academic standing. However, most of the differences in academic achievement and retention status are very small. Overall, the PAS students and the Non-PAS students were highly similar in the level of academic achievement and their retention status at the start of their second year of college. Given that these PAS students were economically disadvantaged, had attended poorer high schools on average and were more likely to be first generation college students, the policy standards developed for this scholarship program succeed very well in identifying students. The policy analysis research conducted to establish the scholarship award criteria identified students with a track record of handling adversity.
The results of this study show that policy analysis research was a useful tool in establishing new scholarship criteria to replace race-based merit awards. Application of the new policy standards produced a cohort of economically needy students who performed well and were retained at rates comparable to the rest of their entering class. More importantly, this cohort of students represented a "new" category of student previously underrepresented at the university. Clearly, students with this level of economic "disadvantagedness" would not have had an opportunity to consider attending a flagship institution in the past. An additional benefit was that this new scholarship program also contributed to the ethnic diversity of the freshmen class. While it is difficult to determine how many of these students would have missed the opportunity to attend a flagship institution without the scholarship offer, it is clear that this entering class of students now contains students who were not part of previous classes of students. We plan to monitor their progress and expect them to graduate in large numbers. The ability to overcome adversity in high school should aid the achievement of their educational aspirations in college.
