It is up to your school's discretion whether or not they will accept our classes for credit. Our classes are not accredited, but we do offer a printable "Completion Certificate" for each level (ASL 1, 2, and 3) of our Online Course (http://online.startasl.com). Our Gold level option includes manual grading/feedback on students' submission assignments as well as any extra documentation their school might need in order to award credit.
Attached you will find the syllabuses for each course level.
Each of the levels of the ASL classes are roughly equivalent to a year of a foreign language in high school and a semester of a foreign language in college. For example, if the student completes levels 1 and 2 of this curriculum, they will have completed 2 years of foreign language credit for high school and 2 semesters of foreign language credit for college. Each level would take a full year to complete in a high school classroom and a semester to complete in a college classroom.
How long it takes to complete the courses depends on the student. The courses are completely self-paced. On average, if a student is very driven, they can complete one course level in one to three months. Most students taking the courses for credit are able to complete one course level in nine months.
At the completion of the course levels, students can be expected to be between conversant and proficient in the language, depending on how much the student is practicing in actual conversation. True language fluency can take up to 3 years or more with regular use.
