This report presents findings from a unique partnership between the University of Michigan and the State that allowed us to match the universe of child maltreatment records in Michigan with educational data on all public school children in the state. We find that roughly 18 percent of third-grade students have been subject to at least one formal investigation for child maltreatment. In some schools, more than fifty percent of third graders have experienced an investigation for maltreatment. These estimates indicate that child abuse and neglect cannot simply be treated like a secondary issue, but must be a central concern of school personnel.
In recent years, policymakers have paid increasing attention to the many ways in which factors beyond school influence a child’s educational outcomes. Indeed, recent research finds that the “poverty” achievement gap – that is, the difference in academic achievement between poor and non-poor children – has grown faster than the racial achievement gap.1 But there is less widespread recognition of the severe traumas that children can face, including homelessness, domestic violence, parental drug abuse, neglect and physical or sexual abuse.
Such trauma is consistently linked to a broad variety of negative life circumstances including poverty, juvenile delinquency, adult crime, low academic achievement, substance abuse, mental disorders and poor health.234 The consequences of early childhood trauma have serious implications for not only the victims, but also families, schools and communities.
The academic struggles of youth in the foster care system have received growing attention.5 And recent work highlights the needs of another group of young people who experience trauma – those who are homeless.6 However, only 4 percent of children with reports of abuse or neglect end up in foster care.7
Here we report findings from a unique partnership between the University of Michigan and the State that allowed us to match the universe of child maltreatment records in Michigan with educational data on all public school children in the state.8 Our work focused on answering the following questions:
- What is the prevalence of child maltreatment investigations (for abuse or neglect) in the public school population by the time students reach third grade?
- Does the risk of maltreatment differ by student race, gender, socioeconomic status or geographic location?
- What is the association between maltreatment and academic performance?
Our findings have important implications for education and social welfare policy in Michigan and beyond. Most importantly, we document that maltreatment is not a problem limited to a small set of children. On average, approximately 18 percent of third grade students has been subject to at least one formal investigation for child maltreatment. In some schools, more than fifty percent of third graders have experienced an investigation for maltreatment. These estimates indicate that child abuse and neglect cannot simply be treated like a secondary issue, but must be a central concern of school personnel.
Data and methods
To create the sample used in this analysis, we matched school records from the Michigan Department of Education to child maltreatment information collected by the Michigan Department of Health and Human Services. Our sample consists of 732,828 Michigan public school students who were born between 2000 and 2006.9
It is worth noting that Michigan ranks pretty highly in terms of the fraction of children who were investigated (see Figure 1). According to the Annie E. Casey Foundation, roughly 66 out of 1,000 children were subject to an investigation in 2015, placing Michigan 6th among states. (This rate of 6.6 percent differs from the 18 percent that we report because the Casey statistic is based on a single year, and the figure we report is based on a child’s cumulative expose from birth to age 9.)
Figure 1 – Children who are subject to an investigation in 2015 (rate per 1,000)
We focus our analyses on students in the third grade, the first year in which the state administers standardized assessments to all children. The measure of child maltreatment incorporates formal investigations relating to potential child neglect as well as abuse (sexual or physical) that occur prior to grade 3. We focus on this time period because young children have significantly higher rates of exposure to maltreatment compared with older children and early maltreatment is thought to have particularly harmful effects on a child’s development.
Formal investigations of child abuse and neglect generally start with a call to the State hotline. Anyone, even a child, can anonymously report a suspected case of maltreatment. These reports are investigated, rejected or transferred to another agency for investigation (e.g. law enforcement). For the investigation to commence, the following criteria must be met: (1) the alleged victim is under 18 years of age, (2) the alleged perpetrator is a parent, legal guardian or other person responsible for the child’s well-being, and (3) the allegations minimally satisfy the child abuse and neglect definitions in the Child Protection Law.10
Approximately 25 percent of formal investigations result in a substantiated complaint. We examine all investigations under the assumption that the existence of a complaint itself may point to some type of trauma even if a formal investigation does not find sufficient evidence for the case to proceed further. We recognize that debate exists about the factors that are associated with reported maltreatment, and how this corresponds with actual maltreatment.1112 For this reason, we replicated all of the analyses reported below using substantiated complaints instead of reported complaints, and found the same pattern of results. Hence, in the current brief we do not differentiate between unsubstantiated and substantiated allegations of maltreatment.
The primary educational outcomes for this study were standardized math and reading scores and grade repetition. In order to assess basic knowledge and skills, we look at whether the child’s performance on standardized math and reading tests meet or exceed the state-defined proficiency level.13 In order to assess social and academic development more broadly, we examine whether the child was ever held back prior to third grade.
In order to disentangle and isolate the effect of maltreatment from factors that are often associated with maltreatment, such as family and neighborhood poverty, we compare students with a history of maltreatment to a group of demographically-matched peers. Specifically, we compared children with complaints for maltreatment to peers who (a) were the same race, gender and birth year, (b) had the same income level as measured by eligibility for subsidized meals, (c) lived in the same neighborhood, and (d) attended the same elementary school.
While this approach allows us to control for many of the circumstances that are associated with both maltreatment and educational outcomes, it cannot account for harder-to-observe factors that could nonetheless play a significant role in a child’s academic progress. The mental health status of adults in a household is an example of one potentially important omitted variable. If, for example, adults struggling with depression, anxiety or other mental health issues are more likely to abuse or neglect their children, the negative effects we report might be overstated. Nonetheless, we believe that the associations shown below provide a useful starting point for understanding the educational consequences of child maltreatment.
Our analyses reveal five key findings that we believe should inform public policy.
Approximately 18 percent of Michigan third graders have been formally investigated by Child Protective Services (CPS) for possible exposure to maltreatment.
African American students, students who qualify for free/reduced lunch (i.e. poor students), students living in relatively high-poverty areas, and students attending urban schools are all more likely to be investigated by Child Protective Services for suspected child maltreatment.
Table 1 shows the prevalence of child maltreatment for various groups of children. Several interesting points stand out.
17.7 percent third grade students attending Michigan public schools had a formal investigation of abuse or neglect by the third grade. Among these students, over one-third (36.0 percent) of the investigations were substantiated. However, as noted above, even unsubstantiated complaints may signal some type of dysfunction within the family.
Investigations for child maltreatment were notably higher for more disadvantaged subgroups. Nearly 1 in 5 students in the free-lunch program (19 percent) had an unsubstantiated investigation and 11 percent had a substantiated investigation. Similarly, those students coming from the poorest neighborhoods had high rates of involvement compared to neighborhoods of medium and high wealth. Students attending urban schools were also more likely to have unsubstantiated (15 percent) and unsubstantiated investigations (10 percent) compared to youth attending suburban schools (9 percent and 4 percent) and town / rural schools (11 percent and 7 percent). And Black students were roughly twice as likely to have had at least one substantiated investigation compared with white students (10.7 percent vs. 5.3 percent).

|% of group with any report||% of group with unsubstantiated report||% of group with substantiated report|
Early childhood maltreatment is associated with significantly lower academic outcomes, even after we control for school, neighborhood, race and other key demographics.
Because children with an experience of early childhood maltreatment come from more disadvantaged families and neighborhoods, one might expect their academic performance to lag behind that of other children. In order to disentangle the influences of poverty from childhood maltreatment, we conducted statistical analyses to control for student demographics as well as school and neighborhood factors.
We find that children who have been investigated for maltreatment perform worse in school than their peers who have not been referred. Moreover, the performance gaps are extremely large. Figures 2 and 3 show how the groups compare in terms of reading and math achievement.
We see that only 57 percent of third graders with a prior CPS investigation achieve basic proficiency levels on the statewide reading exam compared with 65 percent of third graders with no prior CPS investigation. The gap in terms of math proficiency is just as large, with only 44 percent of students with a prior CPS investigation passing the threshold compared with 51 percent among other third graders. These gaps are roughly equivalent in size to the Black-White achievement gap that one finds after controlling for a similar set of neighborhood and school factors.
Figure 4 illustrates that children with a history of CPS investigations are more likely to have been retained than their peers. Sixteen percent of third graders who have no involvement with CPS were held back in kindergarten, first or second grade. In contrast, 23 percent of third graders with a maltreatment investigation were retained – a relative difference of almost 50 percent.
Referral rates vary dramatically across districts, and even across schools within the same district. It is not unusual for one-third of students in high-poverty schools to have been investigated for abuse or neglect.
Figure 5 shows referral rates across 25 large districts in Michigan. We have purposely chosen these districts to include a mix of low-, medium- and high-poverty areas. Districts are shown in descending order of poverty, so that district A (with 90 percent of students eligible for subsidized meals) is at the top and district T (with only 4 percent of students eligible for subsidized meals) is at the bottom.
The darker squares represent the percent of third graders in the district who are referred for a maltreatment investigation before third grade. We can see, for example, that 31 percent of students in district A have been subject to such investigations.
The relationship between student poverty and maltreatment is apparent in the pattern of the squares. In general, districts with higher poverty rates have higher rates of maltreatment investigations. In addition to the variation across districts, there is substantial variation across schools within each district. Each of the lighter circles represents a school within a district.14 For district B, the dark square tells us that on average 32 percent of students are investigated for maltreatment before the third grade. The lighter dots on either side give us information about each school in district B. There are a handful of schools in which the average is less than 32 percent (and as low as 14 percent) and many schools where the average is higher than 32 percent (and as high as 60 percent).
While poorer school districts have higher rates of maltreatment investigations, there are important exceptions to this pattern.
Figure 6 shows the relationship between district poverty rate and maltreatment rate for each of the 542 districts in our sample. The size of the circle reflects the district enrollment. The cluster of dots sloping upward illustrates the association between poverty and maltreatment investigations. It is important to note that these are differences in the number of reported complaints, and not differences in the number (or fraction) of reported complaints that are substantiated. Hence, it is unlikely that the differences shown in Figure 6 are due to disparities in the resources devoted to local child protective services. Childcare workers, medical professional and teachers are all required to report any suspected instances of child abuse or neglect.
However, there are important exceptions. For example, in district W, only 6 percent of third graders had experienced a maltreatment investigation despite the fact that over 75 percent of children in the district are eligible for subsidized meals. On the other hand, in district Z, roughly 28 percent of third graders had been the subject of a maltreatment investigation despite the more moderate 40 percent poverty rate in the district.
Our analysis clearly indicates that early childhood maltreatment is much more common than many lay people suspect. Indeed, the estimates generated in the current study indicate that formal maltreatment investigations are more prevalent than child asthma (8.4 percent), child food allergies (7.6 percent), child disabilities (5.2 percent) and even the combined rate of child and adolescent obesity (17 percent).15
Moreover, the prevalence of child maltreatment is extraordinarily high in some schools. In many Michigan elementary schools, more than one-third of students (and in some cases over half of students) have been the subject of an investigation. Finally, as one would expect, early child maltreatment is a powerful predictor of academic difficulties.
Despite its prevalence and salience for a child’s educational progress, teachers and administrators typically have little formal or confirmed information about child maltreatment – either for an individual child or at the school level. In special circumstances, school personnel may be able to obtain more information about specific children. But in the vast majority of school districts, the data on child maltreatment and foster care is not linked to a child’s educational records.
These findings suggest several important avenues for policy, including the following specific recommendations:
- State officials should design and implement systems to allow for easier and timelier sharing of data between the education system and the child welfare system. In several instances, researchers have been able to link data systems for the purpose of analyses like the current study.16 And, in the case of foster care, some states have now linked data so that school records have some indication of whether a student is currently in foster care. But to the best of our knowledge, no state has established linkages whereby school personnel can easily and systematically determine whether an individual child has been the subject of a maltreatment investigation, or even the prevalence of such investigations within a school.
- School personnel should utilize data on child maltreatment and/or foster care placement to identify students at risk of academic difficulties and provide support for these children.
- Schools or districts with especially high rates of child maltreatment should implement programs specifically aimed at addressing this problem.
A high concentration of children who have been exposed to trauma imposes a substantial burden on teachers and administrators. While there are examples of programs designed to serve foster care youth, we do not know of any such programs designed to serve the broader population of youth who have experienced some form of maltreatment.17
Given the importance of early academic performance, it is critical for school systems to develop ways to support children who have experienced maltreatment. This will require collaboration across education and social service entities to an extent that is rarely seen today.
