Comment on any trend you notice in the data. **Trends in Fourth-Grade NAEP Mathematics Achievement-Level Results**From [National Report Card Mathematics Grade 4](https://www.nationsreportcard.gov/mathematics/nation/achievement/?grade=4)**FIGURE** | Trend in Fourth-Grade NAEP Mathematics Achievement-Level Results**BASELINE**: NAEP Proficient set at NAEP Basic. [Show NAEP Achievement-Level Details]The bar graph illustrates the percentage of fourth-grade students achieving at or above the NAEP Proficient level in mathematics across multiple assessment years from 1990 to 2019. **Descriptions by Year:**- **2019**: 41%- **2017**: 40%- **2015**: 40%- **2013**: 42%- **2011**: 41%- **2009**: 39%*- **2007**: 39%*- **2005**: 36%- **2003**: 32%- **2000**: 24%*- **1996**: 21%*- **1992**: 21%*¹- **1990**: 18%*¹- **1990**: 13%*¹*Significantly different (p < .05) from 2019.¹ Accommodations not permitted.**Note:** NAEP achievement levels are used on a trial basis and should be interpreted and used with caution.The graph provides a visual comparison of student performance over the years, showing a general upward trend in achievement scores, with some fluctuations.

Here we can see that in the above graph, from 1990 to 2019 Neap proficient is increasing.
