After the two year SiSi whole family program, they will have been exposed to about 350-500 Spanish words (depending on how deep they go with their own personal learning dictionaries during the lessons, and the types of activities that are done during the break weeks).  They will be familiar with the present tense, and a litany of other grammar topics.  High School Spanish Level 1 introduces 1000 words, present and preterit tense, and the grammar topics are also about doubled.  So, your child will have been exposed to about HALF of what a Spanish High School Level 1 student will be exposed to.  When they get to 9th grade or so, I still recommend that they begin "at the beginning" of Spanish Level 1.  Their knowledge and depth and ability to speak SOARS as they ZOOM through the first dozen lessons (a whole semester) and feel WONDERFUL that, "I already know more than half of these words, and I can understand EVERYTHING I'm reading and hearing! WOW!"That confidence is what causes their high school scholar-level learning to become truly useful as they move forward on their path to becoming bilingual.For more information on what they will learn in SiSi Level 2 please see the FAQ here or visit the product page description.
