Not all kindergarten curriculums are the same. A few will have students reading simple materials by the end of the year. Your concern should not be concentrated as much on what your child is learning about reading this year, but on what she will be expected to know at the start of first grade.
A chat with the kindergarten teacher should allay any worries that your child will not be ready to handle the first-grade reading activities. Plus, a look at the school's kindergarten and first-grade curriculums should reassure you that there will be a smooth transition between these two levels. You might also want to look at the state curriculum for kindergarten to see that your child's school is following state guidelines. This information is frequently available on a state's Department of Education website.
While you certainly don't need to have your child work on a formal phonics reading program, you should be doing things to reinforce the relationship of letters and their sounds. When you read to your daughter or are doing daily activities with her, point out the beginning sounds of words. And have her identify words that begin with the same sound. Above all else, avoid any phonics activities that only use drills or worksheets. These can turn off children from reading.
