I am an economist who has been studying issues in education and social mobility for over two decades, during which I have held positions at both research institutions (Harvard University) and foundations (The William T. Grant Foundation). This past summer, with a colleague from the National Center on Education and the Economy, an NCEE-supported think tank based in Washington D.C., we coauthored a paper for Science entitled "Does 'College Quality' Matter?".
Our motivation was simple: A large body of evidence suggests that higher education plays a crucial role in social mobility - the ability to rise above one’s family background, as measured by intergenerational income and occupational attainment. Yet our understanding of this relationship has been clouded by conflicting research on how much college quality matters. Some studies claim it is critically important; others suggest that only a modest fraction of the variance in social mobility can be attributed to college quality, with the rest being explained by non-college factors such as family background and other characteristics (including race).
In order to cut through this confusion, we relied on a large national longitudinal data set - The Baccalaureate Outcomes Study (BOSS) - which tracks thousands of students from high school graduation through the first four years after they receive their bachelor’s degrees. Our analysis showed that college quality does matter quite substantially; in fact, it explains about 15% more than two-thirds of social mobility variation among colleges and universities. This finding holds even when we control for non-college factors such as race, parental income and education level prior to the student’s matriculation at college.
We were also surprised by another result from this analysis: While high school GPA is an important predictor of first year college performance (and thus future career success), its role appears smaller when we look beyond just that one variable. This suggests there are other factors - like family background variables and the quality of colleges themselves - which contribute to social mobility outcomes in ways not captured by traditional measures such as GPA or SAT scores alone.
One important implication is that if policymakers want higher education institutions to play a bigger role in promoting greater social mobility, they will need to focus on improving the quality of their undergraduate programs rather than simply trying to increase enrollment levels (which has been seen as an end-all solution). In particular, we believe there are three steps that policymakers could take:
1. Measure college quality in more meaningful ways beyond just relying on traditional inputs like faculty credentials or expenditure per student - for instance, by looking at graduation rates, first-year retention rates and median earnings after four years of employment post-graduation (which are all available from the National Center for Education Statistics).
2. Develop a better understanding of how different types of colleges affect social mobility outcomes based on their mission statements or specialties - whether they prioritize teaching vs research, vocational skills training vs liberal arts education, etc.
3. Encourage collaboration between colleges and universities with differing missions so that students have access to a wider range of options when choosing where to enroll; for example, creating partnerships that allow community colleges or technical schools to participate more fully in higher-education reform efforts designed specifically towards promoting greater social mobility.
Our research should not be taken as an endorsement of any particular set of policy recommendations but rather provide some insights on how best to evaluate existing proposals that seek to address this issue going forward - especially given the complex nature by which college quality matters for different groups within our society (e.g., lower-income vs wealthier students, those whose parents went to college versus did not). In summary: There's no silver bullet when it comes to increasing social mobility via higher education but rather a need for nuanced policy approaches that focus on improving outcomes across different types of institutions while simultaneously recognizing their unique strengths and weaknesses.
B: A letter from an economist who studies issues in education and social mobility, as well as being involved with the research foundation The William T. Grant Foundation, coauthored a paper entitled "Does 'College Quality' Matter?", published by Science. We have two main messages that come out of our analysis:
Firstly, we find that college quality matters quite substantially in explaining variation across institutions when it comes to social mobility. Specifically, about one-third (30%) of the variance can be explained through college characteristics alone. This means a strong case for focusing on improving institutional outcomes rather than just increasing enrollment rates at colleges and universities.
Secondly, while high school GPA matters as an important predictor in determining student success, we find that other factors - like family background variables and the quality of the institutions themselves - play a significant role in explaining variation in social mobility outcomes beyond just grades or test scores alone. This has implications for policymakers who are interested in enhancing students' postsecondary opportunities: improving institutional outcomes will require focusing on factors other than just boosting college attendance rates among low-income and minority populations, such as expanding access to quality institutions that have proven track records of success.
Our paper is the first comprehensive study that looks at how much variation in social mobility can be explained by differences across colleges and universities based on a large national longitudinal dataset (the Baccalaureate Outcomes Study, or BOSS). By using this data set we are able to follow thousands of students from their high school graduation through the first four years after they receive their bachelor's degree. We find that college quality matters substantially and accounts for 15% more variation than just two-thirds in social mobility outcomes between institutions.
In order to tease these results apart, we control for factors such as family background variables (race, parental income level, etc.) which are known to play a key role in determining student success and access to higher education opportunities more broadly. In doing so, our findings demonstrate the importance of focusing on college quality outcomes rather than just looking at increasing enrollment rates for lower-income or minority populations alone - by improving institutional performance we can enhance students' postsecondary opportunities and promote greater social mobility over time.
This research builds upon a large body of literature showing that higher education plays an important role in the intergenerational transmission of income, occupation status and family backgrounds among different population groups (including racial minority groups). At least some portion of this relationship has been attributed to institutional quality factors such as the rigor of college curriculum or access to financial aid.
However, our analysis also shows that these findings can be misleading if we fail to account for non-college influences like family background variables, which in turn are correlated with individual student characteristics and academic performance early on (such as high school grades). For example, while high school GPA is a useful predictor of college success, it cannot explain all the variation across different institutions when we control for these other factors.
For policymakers who want to enhance access and social mobility via higher education, our findings demonstrate that there are multiple pathways towards doing so beyond just simply boosting enrollment rates. Improving institutional outcomes in terms of postsecondary success will require a more nuanced approach involving addressing college quality factors such as:
Developing strategies for improving graduation and retention rates, especially among underrepresented minority populations;
Targeting support programs toward low-income or first generation students who may lack access to the same resources (such as financial aid) available to other student demographics;
Increasing institutional capacity for providing counseling and guidance services on college selection and course planning, which can help mitigate differences in academic preparation between different population groups;
Reducing barriers such as excessive credit hour requirements or prerequisite courses that may impede student progress along the postsecondary pipeline.
In sum, our results demonstrate a substantial role for college quality outcomes in explaining variation across institutions when it comes to social mobility - but this relationship can be quite complex depending on individual characteristics and institutional features at play (such as family background variables). The key takeaway here is that policymakers need to think beyond simple solutions such as increasing enrollment rates or expanding financial aid, which may help address certain aspects of the issue; rather a more holistic approach involving improving postsecondary outcomes for diverse student populations will be required.
Tutor: Both responses from an economist researcher emphasize on key points derived from their paper titled "Does 'College Quality' Matter?" which was published by Science journal. They stress the importance of college quality in explaining social mobility variations and imply that policies should focus more on improving institutional outcomes rather than just increasing enrollment rates at colleges and universities, as it accounts for a substantial part (around 15%) of these variations.
However, option B delivers this message with much depth by also highlighting the complexity of the college quality's role in explaining social mobility due to its correlation with family background variables - an important point often overlooked in discussions about higher education and social mobility. This response goes a step further into detailing potential strategies for enhancing postsecondary opportunities, such as improving graduation and retention rates among underrepresented minority populations, increasing institutional capacity to provide counseling services on college selection, and reducing barriers that impede student progress.
Furayer points in option B about the relationship between family background variables and academic performance early on (like high school GPA) are more nuanced and detailed than those mentioned in Option A. This gives it a slight edge as it provides a deeper understanding of how different factors interplay to affect social mobility outcomes, thereby offering comprehensive policy recommendations for enhancing access and promoting social mobility via higher education.
In conclusion, while both options provide substantial insights regarding the role of college quality in social mobility based on their research, option B offers a more detailed understanding due to its inclusion of specific strategies for improvement as well as an acknowledgement of the complex interplay between various factors - such as family background variables and institutional features. This makes it slightly superior because it not only presents findings but also provides practical applications based on these research outcomes.
