I feel like the tone of this thread mimics the political tone of our country - which makes it so difficult to have meaningful dialogue. Not everyone (I would venture to say most parents) who care about AAP or tests or scores is a crazy, competitive parent who is surely causing irreparable damage to their child. It really is not that extreme and we don't need to take it there. No one said anything about inferiority. The NNAT has some limitations - I think most agree on that. I would love to understand the score better, that's all. Not because I think it defines my child, my child's future or because I want bragging rights. I think seeing a bell curve for our particular population would likely tell me more than a national bell curve. COMPARING students is not a method I invented, comparing students is how the score is derived. |

Here is some data to satisfy your curiosity. It is from 2004-2005, but the total demographics of the second graders in the county has not changed much since then.

Scores are all over the board, even for "in-pool" kids. |
The score is not determined by comparison, only the percentile rank. |
The raw scores are not determined by comparison, but the scaled scores definitely are. The only scores that people care about are the scaled scores. |

The score is not determined by comparison, only the percentile rank. OBVIOUSLY, the number of answers your kid gets right (raw score) is not dependent on what other kids do. Geesh. But the Naglieri Ability Index is a scaled score. |

But the Naglieri Ability Index is a scaled score. The raw score is converted to the scaled score based on the level of the NNAT test given. The scaled score is then converted to the NAI based the child's age at the time the test was administered. |
