describe percentiles, grade-equivalent scores, and scale scores, assignment help

Hello,

this is the description for the question above could you please take a look at it and answer it !!

Please assume that you are a teacher in a school district whose students are required each spring to complete a state-developed accountability test as well as a nationally standardized achievement test. Results of these two tests are reported to each student’s parents during the following summer. In one or both of these tests, the following three reporting indicators are used: (1) percentiles, (2) grade-equivalent scores, and (3) scale scores.

Accordingly, during the initial Parents’ Night of each new school year, you and the other teachers in your school are usually peppered with parental questions about the meaning of these three reporting procedures. Two newly certified teachers at your school have asked you to help them prepare for what they have heard might be a potentially embarrassing interaction during the upcoming Fall Parents’ Night. These two “rookie” teachers confess to you that they know almost nothing about any of the three reporting mechanisms used to describe district students’ performances. You agree to summarize the bare essentials, as well as the pros and cons. You promise to send your summary as an e-mail attachment to the two novice teachers so that they can, if needed, refer back to your description in advance of the approaching Fall Parents’ Night.

Please write up such a description focused on descriptions, advantages, and disadvantages for each test score ( percentiles, grade-equivalent scores, and scale scores) in less than 500 words.

i’m looking for the following in your answer:

1- definition for each type of the test score which are percentiles, grade-equivalent scores, and scale scores.

2- example for each test score ( percentiles, grade-equivalent scores, and scale scores).

3- explanation of the advantages and disadvantages for each test score : percentiles, grade-equivalent scores, and scale scores.

4- you have to read chapter 13 from this link to answer the question thoughtfully : Chapter 13 ” Making sense out of standardized test scores”
