individually nationally normed standardized evaluation

Question

In an Evaluation report for Special education reads,

Findings must be supported by all: x A. individually nationally normed standardized evaluation of the pupil's academic performance

Any ideas on how to translate this?

Answer 1

This is a good context about special education:

"Los resultados deben ser apoyados por todos: individualmente, a nivel nacional, evaluación formal homogénea (or estandarizada or homologada) del rendimiento académico del alumno.

The word "normada" (normed) isn´t on spanish dictionary

Answer 2

Evaluación de norma individual a nivel nacional, estandarizada de acuerdo al rendimiento académico del alumno.
