## Usage

### Loading the Dataset

#### Using Pandas
```python
import pandas as pd

# Load individual splits
train_df = pd.read_parquet('data/train-00000-of-00001.parquet')
val_df = pd.read_parquet('data/validation-00000-of-00001.parquet')
test_df = pd.read_parquet('data/test-00000-of-00001.parquet')

# Load all data
all_df = pd.concat([train_df, val_df, test_df], ignore_index=True)
```

#### Using HuggingFace Datasets
```python
from datasets import load_dataset

# Load from local directory
dataset = load_dataset('parquet', data_dir='data/')

# Access splits
train_dataset = dataset['train']
validation_dataset = dataset['validation']
test_dataset = dataset['test']
```

### Example Usage Patterns

#### Filter by Grade Level
```python
# Get middle school examples (grades 6-8)
middle_school = train_df[train_df['metadata_grade_level'].isin(['6', '7', '8'])]
```

#### Filter by Domain
```python
# Get Life Sciences examples
life_sciences = train_df[train_df['metadata_domain'] == 'Life Sciences']
```

#### Filter by Complexity
```python
# Get proficient-level assessments
proficient = train_df[train_df['metadata_complexity_level'] == 'Proficient']
```

## Educational Standards Alignment

This dataset is meticulously aligned with:
