Definition |
A note about the target audience for the described material. Use primarily when the contents of an item are considered appropriate for a specific audience or intellectual level (e.g., elementary school students). Use to record interest and motivation levels and special learner characteristics. Record information about the target audience and/or intellectual level also in the fixed field element Audn. If both reading grade and interest age or interest grade level information are present, enter codes in Audn based on the interest age or interest grade level information. If a computer file or visual materials record has both reading grade and interest age or interest grade level information present in 521 fields, fixed field element Audn is coded based on the interest age information. Use field 506 if the note is about restrictions on access. For information on punctuation, see the Punctuation section below. |
