K-8 Standardized Achievement Tests: what's out there

I belong to an education mailing list in which someone recently asked about standardized achievement tests for K-8.

Here's the list of what respondents are using.

A couple of principals spoke highly of:

NWEA (and its CPAA and MAP)

Principals also mentioned that they use:

Terra Nova

Stanford Achievement Tests, version 10

CTP

Star 360

Reading A-Z (which is a whole curriculum)

A couple of us said we've seen the Iowas and we don't recommend them.
