Dear &PAR_NAME.EVAL and &STU_FNAME.EVAL &STU_LNAME.EVAL:<br />
<br />
This letter is to inform you that &STU_FNAME.EVAL has the equivalent of 5 or more unexcused absences this school year.  <span style="font-size: 10pt; font-family: arial,sans-serif; color: black;"><span style="font-size: 14px; font-family: arial;">We believe student attendance in school is a key component to school success, so it is very important for all children to develop habits of good attendance. Poor attendance contributes to failing grades, decreased learning opportunities, lower academic achievement and may limit your child's opportunities to be involved with school activities.</span><br />
