Fig. 4: Third grade reading Z-Score† (fitted regression values from Table 3, Model 2) by American Indian status, by duration of exposure to payments before 18 years.

Within the context of the declining trend in third grade reading test scores in this rural population (which mirrors national trends), the race-based disparity in test scores narrows for American Indian children whose mothers had a relatively greater duration exposure. American Indian scores are represented by the orange line. Non- American Indian scores are represented by the blue line.
