    Hello,

    I'm studying NCLB and couldn't sleep trying to figure this out. Please tell me the answer, if you know....

    Given:

    100% of US students must perform at the proficient level in English-Language Arts and Mathematics by 2014.

    Proficient is defined as a score in the 60th-79th National Percentile Rank.

    Question:

    Is it possible for 100% of students to rank in the 60th+ NPR?

    thanks
    iosman

    No... for so many reasons.

    Tell us what you think and why. It is better you learn to think through this information than be given an answer without working for it.

    Percentile rank is a frequency distribution. 60-79th percentile is not a SCORE, it’s a placement on the distribution based on score. Students at the 60th percentile have scored better than 60 percent of those who took the assessment... so no, the goal can not ever be attained.

    well, yes, kinda sorta. In NC percentile is based on previous students' performance. So technically, it is possible for THIS year's students to all perform better than 60% of last year's.
