Summary: This study utilized structural equation modeling to explain mathematics achievement among 6th grade students in Zimbabwe using the Southern African Consortium for Monitoring Educational Quality (SACMEQ) III data. Specifically, the study looked at family background and demographic variables and how they are related to mathematics achievement. The variables included in the model are: homework explained, socio-economic status, number of meals per day, extra tuition, help with homework, given homework, homework corrected, parents’ education, home quality and gender. To fit the model, a path-analytic model using Lavaan Beta 2.1 in R with maximum likelihood estimation with robust standard errors was used. Results showed that the final model was a slightly better fitting model than the hypothesized as measured by three core fit indices, $\mathrm{TLI}=.99$, $\mathrm{CFI}=.99$, $\mathrm{RMSEA}=.012$ $\mathrm{CI}(0.0,0.54)$.
