[单选题]Passage 1 　　In recent years, however, society has cometo understand the limitations of schoolsthat merely sort and rank students. We have discovered that students in the bottomone-third to one-half of the rank order-plus all who drop out before being ranked--fail to develop the foundational reading,writing, andmathematical proficiencies needed to survivein, let alone contribute to, an increasinglytechnically complex and ethnically diverse culture. So today, in asking schools toleave no child behind, society is askingthat educators raise up the bottom of therank-order distribution to a specified level of competence. We call those expectations our academic achievement standards Every statehas them, and, as a matter of public policy,schools are to be held accountable for lakingsure that all students meet them. 　　To be clear, the mission of sorting has not been eliminated from the schooling process.For the foreseeable future, students will still be ranked at the end of high school. However,society now dictates that such a celebrationof differences in amount learned must start at a certain minimum level of achievement for all. 　　The implications of this change in missionfor the role of assessment are profound. 　　Assessment and grading procedures designedto permit only a few students to succeed(those at the top of the rank-order distribution)must now be revised to permit the possibilitythat all students could succeed at some appropriate level. Furthermore, proceduresthat permitted(perhaps even encouraged)some students to give up in hopelessness andto stop trying must now be replaced by othersthat promote hope and continuous effort.In short, the entire emotional environmentsurrounding the prospect of being evaluatedmust change, especially for perennial low achievers. 　　The students' mission is no longer merelyto beat other students in the achievementrace. At least part of their goal must be to become competent. Teachers must believethat all students can acnieve a certain levelof academic success, must bring all of theirstudents to believe this of themselves, must accommodate the fact that students learn at different rates by making use of differentiatedinstruction, and must guide all studentstoward the attainment of standards. 　　The driving dynamic force for students cannot merely be competition for an artificialscarcity of success. Because all students can and must succeed in meeting standards,cooperation and collaboration must come intoplay.The driving forces must be confidence,optimism, and persistence--for all, not justfor some. All students must come to believethat they can succeed at learning if theytry. They must have continuous access to evidence of what they believe to be credible academic success, however small. Thisnew understanding has spawned increasedinterest in formative assessment in recentyears.

Which is meant by the author about the emotional promise of assessment for students?

A. To reach a minimum level of achievement
B. To build up their confidence insuccess
C. To enable them to compete withothers
D. To help them realize their goals
