And here is the "official MFW answer," which I always value, since the Hazells have a lot of experience with their children learning Russian while they lived over there.
- When does My Father's World recommend students begin Rosetta Stone?
My Father's World recommends beginning Rosetta Stone as early as 2rd grader using the Speaking and Listening Course in Rosetta Stone Homeschool. This course allows students to interact without needing to type or read. If students need to hear something again, they can click the audio link button and it will repeat. If the grammar lessons are difficult, these may be easily passed over by the parent.
For 4th-6th graders we recommend using the Extended with Reading Intro Course. This course provides further reading instruction and the opportunity to practice differentiation of pre-typed words and segments. Students do not have to spell directly nor type. Students can do the writing activities or not based on their ability. Parents can simply bypass these or show the student how to do so. You will see a 0 score later for these activities, but it will not affect the performance of the program.
For 7th-12th graders we have developed daily lesson plans that include activities for high school foreign language credit.

Either way, I think Level 1 lasts *most* kids through at least 6th grade, repeating with more of the components each time through. For high school, and some junior highers, Level 1 will only last 1 year.
Rosetta Stone keeps tight control on their prices, no matter which vendor sells it. Prices do go up and down over the year, but that is wholly controlled by Rosetta. I think if you check different vendors on the same day, for the same item, they will all have the same prices. The only time prices will vary from vendor to vendor is when it is a different "Rosetta Stone item" (not counting the MFW lesson plans, which are sent along for free), or when a vendor hasn't gotten around to lowering their advertised price to match the newest Rosetta pricing (but MFW is very fast with that).Ohmomjacquie wrote:Rainbow resource has rs a little cheaper at $123 I think but not the lesson plans that mfw has.
