I'm not a "parent of', but here's my advice...
The headshot should be 8"x10".
The resume should NEVER be more than one page. Trust me, the producers/casting directors will not read the 2nd page. Edit, edit, *edit* everything down to that single page.
Tell the truth on the resume. If your kid hasn't been in that many plays or movies, don't lie about it. Everyone knows everyone in acting, liars are always found out. List your children's training experiences, their dance classes, their workshops, etc.,... all that will show the casting people that your kid is serious about their craft.
The headshot and the resume should be arranged so they are back-to-back. They can either be stapled together at all four corners or the resume can be printed on the back of the headshot. Many times headshots will get lose from the resumes (if poorly-stapled, like maybe just twice on the top edge) & the casting people won't know who that wonderful kid actually *is*. That's why the name should be pre-printed on the picture side of the headshot and the resume should either be attached securely or printed on the headshot.
Your child's name should be pre-printed on the image-side of the headshot.
The resume should be trimmed to fit the headshot.
No report cover.
*Always* take more than materials to an audition than you're told to bring. If the notice says "Bring 1 headshot/resume", bring two or three.
When your child goes in to the audition, make sure they have their h/r's ready to hand to the casting people. They shouldn't be fumbling around in their totebag and wasting people's time.
Do not use those "glamour-shots", a candid snapshot is better than a mall "star-session" photo. No excessive/obvious make-up, natural is best. When your kids go to the audition, if you have daughters, *please* don't put screaming-red lipstick on them. Don't do *anything* to your children that screams "PAGEANT KID".
Break a leg,
agnes!
