Place your tongue tip near the roof of your mouth behind your top teeth. Push air through the narrow gap. No voicing.

Americans pronounce standards as STAN-derdz (/ˈstændərdz/). In "standards", the "a" vowel before M or N raises and fronts toward [eə] — the tongue pulls up and forward, breaking the vowel into a tense glide as it anticipates the nasal. This is called the Cat-Vowel Before M/N, a small move that separates 'classroom' from 'native'. It comes out as STAN·derdz. Stress falls on the first syllable — keep everything else short and quick. You'll hear it in sentences like "The bibliography was formatted according to academic standards" or "All contractors must comply with our safety standards while on site" — more examples below.

The textbook way isn't wrong — it's just not how anyone actually says it.
In "standards", the "a" vowel before M or N raises and fronts toward [eə] — the tongue pulls up and forward, breaking the vowel into a tense glide as it anticipates the nasal. The "/æ/" vowel raises and fronts before M or N — tongue pulls up and forward, producing a tense [eə] glide (between /e/ and /ə/). Not a pure /æ/.
Stress falls on the first syllable, not the others. Stretch STAN — keep everything else short and quick.
Americans use a relaxed retroflex R — the tongue curls back rather than rolling. The R is one continuous sound with the vowel before it, not two separate sounds.
