Not all curricula incorporates testing.TCE, Brainline & Kenweb are are some of those Curriculum Providers that do.

      "The majority of newbies like to have third party confirmation 
& thus choose curricula with testing options.
Also, home schooled children often get the idea that they learn less than
their peers schools. An "outside" test can help to set them right. For this
reason, all purveyors of prepackaged curriculum provide a "test" or
"examination" option, even if they do not themselves believe in testing!

The problem with tests and examinations provided by curriculum suppliers is
the same as the problem with all tests and examinations (except the matric
exam) provided by schools: They have not been standardised, their validity
and reliabilty is unknown and where it has been determined is often dubious.
Most significantly, however: it is easy for an adversary in court to cast
doubts on the reliability of tests provided by curriculum suppliers, because
the supplier has an interest in the outcome of the test. Of course, this
applies to schools as well, but somehow people seem to assume that teachers
are above tweaking the results in order to make themselves look good.

Many families believe in the educational benefits of tests and examinations,
and no doubt, they are right where their own children are concerned. I
believe, however, that standardised tests can serve all the purposes for
which home schoolers want "testing". In addition, they are the only tests
that generate data that can be useful for foresic purposes if one schould
have to make the point in court."

      It is suggested that standardised tests are taken every 3 years (by an independent Educational Psychologist). Oikos Ministries & Martie du Plessis (Dynamis) could be consulted in this regard.

"The things you want tested are language (first and second language - if any)
and math.

These are the "contentless" subjects, en the sense that they would normally
be independent of what books or system you use. The tests are standardised,
which means they have been normed to a particular reference group of
children (e.g."South African" or "Eastern Cape" or "rural Mpumalanga") some
claim to be "internationally normed", which is a bit diffucult.

Most of the stuff is "monkey puzzle", although you can expect little tasks,
manipulations, and interview questions as well, especially with young children.

Performance on math and language tests generally are considered sufficient
to indicate a child's general performance. (The American SAT tests generally
used for university entrance test either language - English - and math or
language and science.)

If you want the tests as an outside opinion to satisfy "the outside"
(including mother-in-law) I would recommend strait forward scholastic tests
in language and math and nothing else.

In any event, you are likely to find that the psychologist does not tell you
anything you did not know beforehand. The point being that, working with
your kids daily you know what they can do and what not.

If your psychologist seems uncertain of what is required (a lot of them do)
tell them to phone Professor Elsabe Roets at Unisa +27 12 34 77557
(afternoons) or +27 83 302 0590 (cell). She has a lot of experience of this
kind of thing, and most helpful."
