This general achievement trends profile includes information that the Center on Education Policy (CEP) and the Human Resources Research Organization (HumRRO) obtained from states from fall 2008 through April 2009. Included herein are: (1) Bullet points summarizing key findings about achievement trends in that state at three performance levels--basic and above, proficient and above, and advanced; (2) Background information about limitations of the state's test data and characteristics of the state's testing system, including major changes in its testing system; and (3) Figures and tables with the percentages of students scoring at the proficient level and above for all years with comparable data since 1999 and for all grades tested under the No Child Left Behind Act. Between 2003 and 2008 in reading, and between 2002 and 2008 in math, the percentage of Nebraska students scoring at the proficient level and above showed a moderate-to-large increase in both subjects at all three grade levels analyzed. Information on the percentages of students performing at the basic and advanced levels is not available. (Contains 2 figures and 2 tables.)
