You should speak to the principal or the curriculum specialist in the school if you have questions on how the immersion program is implemented. At my dds school, they have 2 language arts classes (one in English and the other in Spanish), Math is taught in English, Social Studies/Science in Spanish. The program stops at 5th grade. My dds can read and comprehend Spanish at about a 2nd grade level (they are in 3rd grade). They don't practice speaking it much because they prefer speaking English; however, they speak it without an accent and can communicate in Spanish when they have to. For instance, when someone asks them a question in Spanish, they usually understand them and can respond. My dds do sometimes struggle with their Spanish work, but on the other hand, their English work is a breeze for them. I consider it enrichment for my dds. I grew up bilingual, so I wanted to my dds to have the opportunity to learn a second language at an early age. GL! -- Gloria
