Not so much a complete curriculum as a collection of texts, Christian Liberty's history program focuses on the United States until the later grades and maintains an emphasis on God's hand in history throughout. All of the texts are illustrated (some in black and white, some in color) and feature easy-to-read text. While the books (particularly for the younger grades) leave some noticeable gaps, the authors weren't trying to provide comprehensive coverage and encourage parents to supplement with outside resources.
Student texts are accompanied by either an answer key or a teacher's manual. Answer keys provide answers to in-text and test questions; teacher manuals include the same, as well as lesson plans and background information. While the teacher manuals aren't absolutely necessary, they are inexpensive and include a lot of useful material. Tests include multiple choice, true/false, and "matching" questions.
Out of ten texts, seven cover American history. World history is introduced for the first time in sixth grade, and is limited to the European Middle Ages. If you follow CLP's plan, between the Streams of Civilization texts and the Bob Jones U.S. history text for grades 11-12, your student will have two years of world history in high school. (BJU's World Studies text is used for seventh grade.) For the Bob Jones texts they use, CLP has designed their own tests and answer keys.
The flow of the CLP history program is as follows:
Because of the disparity between the amount of U.S. and world history covered, if you're going to use the entire program we'd strongly encourage you to supplement with outside materials, particularly those oriented toward world history. Individually, most of the texts are excellent, and if you're looking for a firm Christian approach, this program certainly has it. History for Little Pilgrims, The Story of the Constitution and The Land of Fair Play, and the Streams of Civilization books are particularly good for both history coverage and Christian content. The main problem with CLP history as an overall course of study is it seems haphazard, mostly leaning towards American history except for the random Middle Ages at 6th grade, before borrowing world history material from A Beka or Bob Jones in grade 7; if you use the (we believe superior) BJU World Studies text, you'll never really study ancient history until high school.
Since the course is not coherent, it would be very easy to use the texts you favor to supplement or in place of another curriculum. These are some of the most readable history texts you'll find. Other than the Streams of Civilization books, each text is written in a conversational, accessible style that will have even reluctant history students reading avidly to find out what happens next.
