With over 50 million Americans living at or below the poverty line (Oxfam, 2019), poverty is a social issue that is endemic across the United States of America (USA). Those living in poverty face challenges in accessing healthcare, education and food—things many take for granted. In addition, over 50 million Americans are food-insecure, meaning they lack consistent access to enough food to lead an active, healthy life (Gundersen, 2013). This results in children and students going to bed hungry at night. Often times, a school breakfast will be their only meal for the day. Living in poverty means these students are less likely to finish high school or college, which may further influence their lifestyle as adults, including job prospects, decisions around diet, recreational activities, and substance use (Lacour and Tissington, 2011; Ladd, 2012). In addition, poverty and low socioeconomic status (SES) are associated with visible low social status, and this can be a source of intrinsic chronic stress, increasing vulnerability to distress and potentially destructive coping mechanisms (Mulia et al, 2008).
SES, which is a measure based largely on income, education and occupation, is a major social basis for inequalities and an important predictor of an individual's health, career and lifetime earnings. Low SES is strongly associated with lower educational attainment (Lacour and Tissington, 2011; van der Berg, 2008), and this association is observable across data from local to national levels (Ladd, 2012). Students from low SES households are more likely to experience food insecurity (Dean and Sharkey, 2011), which is strongly associated with precarious housing status (Hughes et al, 2011; Silva et al, 2017; Goldrick-Rab et al, 2018) and is, in turn, related to lower academic success (Roustit et al, 2015). An estimated 25–36% of post-secondary students suffer from food insecurity (Silva et al, 2017), more so in the community college population (Goldrick-Rab et al, 2018). If students are food-insecure, they may face difficulties in their educational pursuits.
Considering that socioeconomic issues exert such influence on student performance, educators should remain aware of such issues within their student population. Educators who are unaware of these influences may be less likely to connect students to appropriate supports to foster success. Unless educators appropriately support students from low SES backgrounds, paramedic training programmes risk precipitating a cycle that makes them less likely to enrol in college in the first instance, more likely to fail out and less likely to have formal qualifications, when compared to their peers from higher SES backgrounds (Blanden and Gregg, 2004; National Student Clearinghouse, 2016). Lack of support ultimately negatively affects adult working life, in terms of both income and working hours (Duncan et al, 2012; Duncan et al, 2017)
Importantly, this means that support—both from inside and outside of educational institutions—is essential. If students lack adequate support at home from family and peers, this can present a further barrier to their educational attainment (Engle, 2007). As a result of parents' own education level, and the chronic stress associated with poverty and low SES, families living in high-poverty, high-unemployment and low-education neighbourhoods are likely to employ fewer education-oriented practices with their children (Greenman et al, 2011). Evidence shows that increased parental involvement in academic matters can mitigate some of the effects of low SES (Greenman et al, 2011). Increased family support has been demonstrated to directly influence overall academic achievement and retention rates at the community college level (Kuh et al, 2006).
Many paramedic programmes are delivered through the community college system. Therefore, it is a source of concern that many paramedic programmes may not routinely collect or use the available information related to student SES. While the relationship between individual SES and academic performance in paramedic students remains unclear, there is strong evidence from the broader literature to suggest that low SES can result in negative effects on academic performance (Ladd, 2012). Paramedic education programmes need to collect and use this data; otherwise, educators will remain blind to the effects of SES on students. Additionally, students from certain geographical areas may face challenges when they enter paramedic education programmes because of the local socioeconomic climate. It is highly unlikely that all students from a low SES background would report such issues, because of the significant stigma associated with poverty and low SES.
In light of the ease of availability of county-level SES data, the authors proposed to investigate if these data could be used to uncover some of the concerns highlighted in relation to poverty, income, food insecurity and parental education, specifically with regard to paramedic students. These insights will then be used to explore potential solutions for consideration.
Aim
This study sought to examine the relationship between paramedic student academic performance and county-level SES indicators. Additionally, the authors sought to examine the relationship between a paramedic applicant's parental education level and the applicant's entrance exam scores. It was hypothesised that paramedic students from counties with lower SES (as defined by median income, percent living below the poverty line, percent of food insecurity and high school graduation rate) would demonstrate lower performance on exams, when compared with students from counties with higher SES (as defined by the same criteria). It was also hypothesised that lower parental education level would be associated with lower applicant entrance exam scores.
Methods
Ethics approval
This study was conducted with ethics approval from Inver Hills Community College in Grove Heights, Minnesota.
Data collection
Data were acquired for paramedic students with accounts in Fisdap, an internet-based emergency medical services (EMS) education administrative database in the states of California, Virginia, Louisiana, Texas and Mississippi. These states were selected to allow for variation in SES, as well as an adequate number of paramedic programmes that enter data into Fisdap. In addition to basic demographic data, entrance exam (EE) scores from September 2018 to January 2019 were collected for these students. Parent education level was also collected from EE data. Paramedic Readiness Exam (PRE versions 3 and 4) scores, from 2011 to 2019, were also obtained for these students. Only scores from the first attempt at the PREs were counted. Publicly accessible SES data for all counties within the identified states were acquired from the Robert Wood Johnson Foundation County Health Rankings for 2017, and US Census data. ZIP code data were converted to county for each state via an online US ZIP Code lookup tool.
Inclusion and exclusion criteria
Records from students who had indicated their consent for research had complete demographic information, including ZIP code, and who had made at least one attempt on the EE, PRE3 or PRE4 (not all programmes use all exams) were included in the analyses. Records from students who did not give consent for research, that had incomplete demographic data, or missing ZIP code information were excluded from analyses. Only first-attempt scores were included, and counties with less than five reported scores were excluded.
Data analysis
Statistical analyses were performed in R (R Core Team, 2019). A multiple linear regression analysis was performed using PRE3 and PRE4 scores, combined with income, poverty level, high school graduation rate and food insecurity data to determine predictive relationships between these variables. To obtain the relationship of each parental educational level EE score, a one-way analysis of variance (ANOVA) was conducted, with score as the dependent level and the parent education level (with six levels) as the factor. Continuous variables are presented as means, median, standard deviations (SD). P<0.05 was considered statistically significant.
Definitions
The following definitions are used in the County Health Rankings Report (Robert Wood Johnson Foundation, 2019), and the US Census Data (United States Census Bureau, 2019), and are applicable to the data and discussion in this study:
Results
PRE3 data
There were 3697 records from the five states. These were aggregated to calculate the mean score and number of results by county. The final data set used for analyses (counties >5 reported scores) consisted of data from 151 counties.
PRE4 data
There were 1293 records from the five states. These were aggregated to calculate the mean score and number of results by county. The final data set used for analyses (counties >5 reported scores) consisted of data from 60 counties.
EE data
There were 3607 records from students who took the entrance exam between September 2018 and January 2019. Table 1 outlines the characteristics of included data (number of records, mean score, number of counties, etc).
Exam | n (records) | Mean score | SD | n (counties) | Mean reports per county | SD | Range |
---|---|---|---|---|---|---|---|
PRE3 | 3697 | 69.76 | 9.13 | 151 | 20.25 | 28.4 | 5–237 |
PRE4 | 1293 | 72.1 | 7.2 | 60 | 14.68 | 12.38 | 5–77 |
EE | 3607 | 79.26 | 8.65 | - | - | - | - |
A linear multiple regression model was conducted to determine the relationship of each SES variable to PRE3 score. The model was PRE3 Score ~ Income + GradRate + Poverty + Food. The results of the regression are presented in Table 2. Results indicated there was a significant collective relationship between income, poverty, graduation rate, food insecurity, and PRE3 scores, (F(4,143)=10.66, P<0.001, R2=0.23). The individual predictors were examined further and indicated that income (t=5.36, P<0.001), graduation rate (t=-3.01, P<0.01), poverty (t=2.28, P<0.05) were significant predictors in the model. Figure 1 demonstrates the relationship of each of the four SES variables with the PRE3 score. The y-axis measures the PRE3 score, while the x-axis measures the individual predictors.

High school graduation rate | -0.14 | 0.05 | -3.01† |
Poverty | 0.11 | 0.05 | 2.28‡ |

Residual standard error: 3.771 on 143 degrees of freedom (three observations deleted because of missingness) Multiple R-squared: 0.2296, Adjusted R-squared: 0.2081, F-statistic: 10.66 on 4 and 143 DF, P<0.0001.
To determine the relationship of each SES variable to PRE4 score, a linear multiple regression model conducted. The model was PRE4 Score ~ Income + GradRate + Poverty + Food. The results of the regression are presented in Table 3. These results indicate that there was a collective significant effect between income, poverty, graduation rate, food insecurity, and PRE4 scores, (F(4,54)=4.72, P<0.01, R2=0.26). The individual predictors were examined further and indicated that income (t=3.71, P<0.001) was the only significant predictor in the model. Figure 2 shows the relationship of each of the four SES variables with the PRE4 score. The y-axis measures the PRE4 score, while the x-axis measures the individual predictors.

(***=p<0.001). Residual standard error: 2.841 on 54 degrees of freedom (one observation deleted due to missingness), Multiple R-squared: 0.2592, Adjusted R-squared: 0.2043, F-statistic: 4.723 on 4 and 54 DF, p-value: <0.01.
Entrance exam
The boxplots in Figure 3 show the distribution of entrance exam scores by parent educational level. The y-axis measures the EE score, while the x-axis measures the parent education level.

Parent education level: A=High school diploma or less; B=Some college; C=Trade certification; D=Associate's degree; E=Bachelor's degree; F=Graduate degree (Masters, PhD).
The one-way ANOVA for parental level of education and EE score was statistically significant (F(5,3601)=18.23, P< 0.001). Students whose parents had a high school diploma or less had the lowest EE scores (Group A, mean=77.42, SD=9.21), while students whose parents had a graduate degree had the highest EE scores (Group F, mean=81.55, SD=8.22).
Discussion
This study demonstrated that county-level SES indicators, in particular, a combination of income, poverty level, high school graduation rate and food insecurity, had a significant relationship with paramedic student academic performance. Median household income is a well-recognised indicator of income and poverty, and this income at a county level was significantly related to exam scores in both PRE3 and PRE4 exams. With one in four children in the USA living on or below the poverty line (Oxfam, 2019), this is a cause for concern. Parental academic achievement was significantly associated with EE scores in this study. This is significant because of previous research that demonstrated that performance on the EE positively predicted first-time pass rate on the National Registry of Emergency Medical Technicians Cognitive Exam (Page et al, 2015), and was associated with performance on cardiology and airway unit exams (Page et al, 2013). EE performance was also associated with graduation success in paramedic programmes (Renkiewicz et al, 2015).
There is significant stigma attached to lower SES (Stewart et al, 2009; Williams, 2009; Johnson et al, 2011), which may present as a barrier to individual students seeking assistance. To remove such barriers, paramedic programmes may consider interventions such as online resources regarding income support, the provision of scholarships, and access to confidential counselling and support services. In addition, programmes should endeavour to highlight the availability of existing resources within the larger college or university community. These may include resources such as financial aid, health plans, legal advice, used book stores, bike shares, and transit passes.
Paramedic programmes in the USA and Canada are often delivered through community colleges, and such students are more likely to go a day without eating than their university counterparts (Goldrick-Rab et al, 2018). Food insecurity and housing instability can negatively affect classroom attendance, academic performance and the ability to continue in higher education (Broton and Goldrick-Rab, 2016; Goldrick-Rab et al, 2018). Paramedic programmes may need to consider implementing interventions such as food banks, sharing shops, breakfast clubs, information on food supplementation, and rent and meal subsidies where appropriate.
Despite the evidence that SES affects student academic performance, paramedic programmes in these jurisdictions do not routinely collect information on the individual SES of their students. It remains unclear what type of relationship exists between individual SES and individual academic performance of paramedic students. This study suggests that paramedic programmes should attempt to collect individual SES data from students that can then be used to identify issues and mitigate any potential effects of SES on academic performance. Such data would need to be collected and acted upon in confidence.
Limitations
The results presented are subject to several limitations. The study was limited to data obtained retrospectively, from self-reported demographic data, and first attempt at entrance, PRE-3 and PRE-4 paramedic exams submitted to Fisdap. Not all paramedic programmes in the USA use the Fisdap database and testing products. The sequence of tests, and the conditions under which the tests were conducted (proctored, open-book, timed, etc) cannot be determined from the Fisdap data. Students may have entered their programme or work address instead of their home address. Counties and ZIP codes generally contain significant variability in SES, and this cannot be accounted for in our data. County-level data also do not reflect individual student SES, which is a more accurate predictor of individual student success. There is no prior evidence these data exist, hence the use of surrogate data markers. Counties that had less than five reported scores and records that were missing ZIP codes were excluded from analysis.
Conclusions
This study has demonstrated that county-level SES factors are associated with paramedic student academic performance. While this study used county-level data as a surrogate for individual student SES, it does provide some insight into the potential effects that a student's background may have on their academic performance. Accepting that the results need to be interpreted in the context of the significant limitations of such an approach, given the lack of other avenues by which to explore this issue, the authors believe that the results nevertheless improve the paramedic community's understanding of the issue. The results of this study also serve to highlight for the first time within paramedic education the identified role of SES on academic performance. This issue remains (anecdotally) poorly addressed within paramedic education programmes. Given the evidence that SES can impact academic performance in general, this study supports the collection of individual student level SES data, to accurately identify and address its effects on student success in education programmes.
