Reliability and validity are two critical ideas for understanding standardized tests.

信度和效度是理解标准化测试的两个关键概念。

There are additional levels of these dimensions, but these three have best withstood scientific tests of reliability and validity across infants, children and teenagers.

这些维度还有其他层次，但这三个维度最能经受住婴儿、儿童和青少年的信度和效度科学测试。

And again, it's a real art going through the details of how to do that but the broad answers involve reliability and validity.

再次强调， 这确实是一种艺术， 需要对如何做到这一点的细节有深入的了解， 但大致的答案涉及可靠性和有效性。

The reliability and validity of a test is determined, in part, by just how well it does at predicting your future performance on the test and your real world performance.

考试的可靠性和有效性，部分取决于它在预测你未来的考试成绩和实际表现方面的准确程度。
